Description
Technical Field
The invention relates to the technical field of circuit design, in particular to a brushless direct current motor driving system for a space flywheel.
Background
The space flywheel is a common actuating mechanism of the satellite attitude control system, and the satellite attitude control is realized by outputting reaction moment in a momentum exchange mode. The space flywheel generally adopts a brushless direct current motor, as shown in fig. 1, a current common driving circuit topology diagram of the brushless direct current motor for the flywheel adopts 4 high-low side driving control chips U1-U4 to control switching tubes Q1-Q8, and realizes on-off control of a brushless direct current motor winding UVW. The high-side control Q1 of U1 and the low-side control Q8 of U1 cannot be realized by adopting a bootstrap circuit due to higher low-side voltage, so that the high-side power supply of the chip is realized by adopting isolated DCDC. Because the isolated DCDC device is easily influenced by space irradiation environment, the isolated DCDC device for space needs special design and reinforcement treatment, has higher cost and larger volume, and has adverse effects on the volume, weight and cost of the flywheel.
In addition, the switching tube Q1 is only used as a switch in the current common design, and the motor driving control mainly uses Q2-Q7 for PWM control, and the mode enables the busbar voltage to directly act on the motor winding, so that the torque pulsation is larger when the motor rotates, the flywheel control precision is influenced, the micro-vibration aggravates the abrasion of bearing parts, and the service life of the flywheel is influenced.
In addition, in the current common design, the energy consumption circuit adopts Q8 single-tube modulation, the energy consumption resistor R1 is a fixed value, and most of the power generated by the energy consumption braking at high speed is converted into the thermal power of R1 for protecting the motor winding, so that the resistance value of R1 is at least twice the resistance of the motor line generally. Because the R1 value is larger, in order to ensure that the acceleration of the dynamic braking meets the use requirement, the switching point of the speed of the dynamic braking and the reverse braking is generally larger, such as a flywheel with rated rotation speed of 6000rpm, the switching point is about 2000rpm, the torque pulsation near the switching point is larger, and the flywheel is generally operated at about 2000rpm, so that the control stability of the flywheel is poor, and the reverse braking needs to be powered by an external power supply, so that the power consumption is larger.

Alternatively, the resistances of the resistor R4 and the resistor R84 may be 27Ω; the capacitance C3 may be 0.1 μf.
The drive control circuit U1 comprises a first high-side bootstrap circuit and a voltage stabilizing circuit, the first high-side bootstrap circuit and the voltage stabilizing circuit in the drive control circuit U1 jointly provide power for the high side of the drive chip U1, the low-side power supply +12V realizes the high-side bootstrap power supply through a fast recovery diode D2 and a nonpolar capacitor C2, the voltage stabilizing circuit is used for realizing high-side voltage stabilizing 13V power supply through R5, R6 and a voltage stabilizing tube D3 at the moment when the BUCK voltage reducing circuit starts to work, the high-side voltage stabilizing 13V power supply is realized by a bus power supply VCC, the first high-side bootstrap circuit is used for stably providing a power supply loop after the BUCK circuit stably works, high-side power supply is continued, and stable power supply of the U1 at any moment is ensured.
Specifically, the first high-side bootstrap circuit includes: the diode D2 and the capacitor C2 are used for realizing high-side bootstrap power supply of the drive control chip U1; the low-side power supply 12V is connected with the anode of the diode D2, and the cathode of the diode D2 is respectively connected with one end of the capacitor C2 and the high-end floating power supply Voltage (VB) of the driving chip U1; the other end of the C2 is respectively connected with the high-end floating power supply offset Voltage (VS) of the driving chip U1 and the source electrode of the switching tube Q1;

Referring to fig. 2 and 7, the driving control circuit U5 of the brushless dc motor driving system for a space flywheel controls the secondary energy consumption control circuit, and is used for performing secondary energy consumption braking at a medium and low rotation speed by using the secondary energy consumption control circuit in a braking mode of the brushless dc motor for a flywheel within a rated rotation speed range. Specifically, the flywheel secondary energy consumption control circuit comprises a switching tube Q9 and a resistor R3, wherein the grid electrode of the switching tube Q9 is connected with the low-end output (LO) of the driving control circuit driving chip U5, the drain electrode of the switching tube Q9 is connected with the output Vswing of the BUCK voltage reduction circuit through the primary energy consumption resistor R3, and the source electrode of the switching tube Q9 is grounded.
The size of the resistor R3 is related to the resistance value of the motor wire, preferably, the resistance value of the secondary energy consumption resistor R3 is within 50% of the resistance value of the motor wire, the lower limit of the secondary energy consumption operation rotating speed is ensured to be reduced to be within 10% of the rated rotating speed as much as possible, and the aim of reducing the energy consumption and reverse connection speed switching point is fulfilled.
The brushless direct current motor for the flywheel needs to ensure that acceleration and deceleration are controllable within the rated rotating speed range, so that the operation can be divided into a driving mode and a braking mode, and the braking mode can be divided into a primary energy consumption braking mode, a secondary energy consumption braking mode and a reverse braking mode according to the current rotating speed, wherein the primary energy consumption braking mode is used at a high rotating speed, the secondary energy consumption braking mode is used at a medium and low rotating speed, and the reverse braking mode is used at a low rotating speed.
Since the forward and reverse rotation control process is substantially identical, hereinafter, the operation process of the driving circuit for controlling the forward rotation of the motor will be described in detail in a specific embodiment.
1) The flywheel starts from rest and accelerates from positive rotation, the drive control circuit U1 controls the switching tube Q1 according to the front end input signal PWMQ1 to carry out PWM switching operation, the drive control circuit U1 controls the switching tube Q8 to be turned off, so that voltage regulation control from VCC to Vblank is realized, and at the moment, high-side power supply of the drive chip U1 is mainly provided by a first high-side bootstrap circuit; the driving control circuits U2 to U4 respectively control corresponding switching tubes Q2 to Q7 according to front-end input signals PWMQ2 to PWMQ7, so that forward commutation conduction of the motor is realized; meanwhile, the driving control circuit U5 controls the switching tube Q9 to be turned off. At this time, the motor Current is converted into a voltage signal current_v through a sampling resistor R2, and the front-end circuit reads the signal and calculates to output a proper PWM signal to realize the controlled acceleration operation of the motor.
2) The flywheel is decelerated under a high-speed state, the flywheel works in a primary energy consumption braking mode, the driving control circuit U1 controls the switching tube Q1 to be turned off, the BUCK step-down circuit stops working, the driving control circuit U1 controls the switching tube Q8 according to a front-end input signal PWMQ8 to perform PWM switching operation, the driving control circuits U2-U4 control the switching tubes Q2-Q7 to be turned off, and meanwhile the driving control circuit U5 controls the switching tube Q9 to be turned off. At this time, the motor current passes through the body diode of the switching transistors Q2 to Q7, the resistor R1, the switching transistor Q8 and the sampling resistor R2, and most of the power consumption is consumed through the resistor R1 due to the large resistance of R1, so that the energy consumption braking of the motor is realized. Meanwhile, the front-end circuit reads the voltage signal current_v and calculates in real time so as to output a proper PWM signal to realize the Current controllability of the motor, thereby realizing the controllability of the primary energy consumption braking of the motor.
3) The flywheel is decelerated under a medium-speed state, the flywheel works in a secondary energy consumption braking mode, the driving control circuit U1 controls the switching tube Q1 to be turned off, the BUCK step-down circuit stops working, the driving control circuit U1 controls the switching tube Q8 to be turned off, the driving control circuits U2-U4 control the switching tubes Q2-Q7 to be turned off, and meanwhile the driving control circuit U5 controls the switching tube Q9 according to a front-end input signal PWMQ9 to perform PWM switching operation. At this time, the motor current passes through the body diode of the switching tubes Q2 to Q7, the resistor R3, the switching tube Q9 and the resistor R2, and since the motor is at a medium speed at this time, the reverse motor is smaller, and if the second-stage energy consumption resistor R3 still uses the same resistance value as the first-stage energy consumption resistor R1, a sufficient motor current cannot be generated, so that the resistance value of the second-stage energy consumption resistor R3 should be greatly reduced, preferably less than half of the resistance of the motor wire, and most of the power consumption is consumed through the motor winding at this time, thereby realizing the second-stage energy consumption braking of the motor. Meanwhile, the front-end circuit reads the voltage signal current_v and calculates in real time so as to output a proper PWM signal to realize the Current controllability of the motor, thereby realizing the controllability of the secondary energy consumption braking of the motor.
4) The flywheel motor is decelerated in a low-speed state, and if the secondary energy consumption is continuously used, the generated motor current is too small to meet the control requirement, so that a reverse braking mode is needed. At this time, the driving control circuit U1 controls the switching tube Q1 according to the front end input signal PWMQ1 to perform PWM switching operation, the driving control circuit U1 controls the switching tube Q8 to be turned off, so that voltage regulation control from VCC to Vblank is realized, at this time, the high-side power supply of the driving chip U1 is firstly supplied by the voltage stabilizing circuit, and after the BUCK circuit stably operates, the bootstrap circuit supplies power; the driving control circuits U2 to U4 respectively control corresponding switching tubes Q2 to Q7 according to front-end input signals PWMQ2 to PWMQ7, and conduct control according to motor reverse commutation logic; and meanwhile, the driving control circuit U5 controls the Q9 to be turned off. At this time, the motor Current is I-V converted into a voltage signal current_V through a sampling resistor R2, and the front-end circuit reads the signal and calculates to output a proper PWM signal to realize the motor controlled reverse braking operation.
