Description
Technical field
The utility model relates to a kind of dynamical system, particularly relates to a kind of electric machine control system.
Background technology
Brshless DC motor, due to its brushless, low interference, noise is low, smooth movements, the advantages such as life-span length, low maintenance cost, are used in control overflow higher, on the equipment that rotating speed is also higher usually, as model plane, unmanned plane etc. control strict to motor speed, rotating speed reaches very high equipment.
In prior art, the application of brshless DC motor in model plane, unmanned plane etc., adopts open loop control mode more, for controlling motor speed.We know, in order to reach good flight stability and mobility, and the velocity amplitude that motor speed needs real-time following controller to set.
But, when being applied in aircraft, motor speed be vulnerable to external environment condition as jolted, the impact of the factor of air-flow, vibration aspect.If the open loop control mode just by adopting in prior art, the control command that motor driver receives is throttle amount, only can realize when motor speed improves rotating speed fast lower than during rotating speed of target, the rotating speed of target value of actual needs can not be set, and when motor actual speed is higher than rotating speed of target, quick reduction of speed can not be realized because screw and motor have higher rotational kinetic energy, and then good flight stability and mobility can not be obtained.Therefore, the motor speed of aircraft is easily interfered, and model-following control order that can not be good, control effects is undesirable.
Utility model content
The technical problems to be solved in the utility model is model-following control order in order to motor not made good when overcoming in prior art the rotating speed controlling motor and the defect causing control effects undesirable, provides a kind of electric machine control system.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of electric machine control system, its feature is, comprise a controller and some Power Components, each Power Component comprises a motor driver and a motor, described Power Component is all electrically connected with described controller, described motor driver and the electrical connection of described motor, described controller sends a rotating speed of target signal to described motor driver, described motor driver detects the actual speed of described motor in real time, and described motor driver receives the backward described motor of described rotating speed of target signal and exports a correction rotating speed drive volume.
In this programme, rotating speed of target characterization one rotating speed of target value, the difference that motor driver can be formed according to this rotating speed of target value and actual speed value, and set a controling parameters, adopt the mode of closed-loop control, export one to motor and correct rotating speed drive volume, correct rotating speed drive volume and characterize a correction tachometer value, motor regulates the rotating speed of self according to this correction tachometer value, to reach rotating speed of target value, thus achieve the model-following control of motor, and can the control command that sends of following controller well, therefore control effects is desirable.
Preferably, the quantity of described Power Component is 4,6 or 8.
Preferably, described motor is brshless DC motor.Brshless DC motor is abbreviated as BLDC (Brushless DC Motor), and it has the characteristic of brush direct current motor, and brshless DC motor can improve the control accuracy to its rotating speed further with the advantageous characteristic of himself.
Preferably, aircraft can be made when described electric machine control system is applied in aircraft to show splendid flight stability and mobility.
Preferably, described electric machine control system also comprises a bus, and described Power Component is all electrically connected with described controller by described bus.
Positive progressive effect of the present utility model is: by controller, annexation between motor driver and motor, adopts the mode of closed-loop control motor, makes motor can the control command that sends of following controller well, and therefore control effects is desirable.
Accompanying drawing explanation
Fig. 1 is the structural representation of electric machine control system of the present utility model.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
The present embodiment provides a kind of electric machine control system, described electric machine control system is applied in aircraft, as shown in Figure 1, comprise a controller 1, 6 Power Components and a bus 2, obviously, need to power to each Power Component, also namely have power line 3 to exist, each Power Component comprises motor driver 4 and a brshless DC motor 5, described Power Component is all electrically connected with described controller 1 by described bus 2, described motor driver 4 and described brshless DC motor 5 are electrically connected, described controller 1 sends a rotating speed of target signal to described motor driver 4, described motor driver 4 detects the actual speed of described brshless DC motor 5 in real time, described motor driver 4 receives the backward described brshless DC motor 5 of described rotating speed of target signal and exports a correction rotating speed drive volume.
In order to make the structure of clearer this electric machine control system of understanding of those skilled in the art's energy, further aid illustration is done to the control procedure of the present embodiment: controller sends a rotating speed of target signal to motor driver, motor driver obtains this rotating speed of target value, motor driver detects the rotating speed of brshless DC motor in real time, and set a controling parameters, when the actual speed of brshless DC motor is higher than rotating speed of target, illustrate that the rotating speed of current brshless DC motor is too fast, need brake to reduce rotating speed fast, the correction rotating speed drive volume then exported by motor driver as reduction how many rotating speeds determines, with the rotating speed of target that following controller sends, and when the actual speed of brshless DC motor is lower than rotating speed of target, then illustrate that the rotating speed of current brshless DC motor is too slow, need to improve rotating speed by improving throttle amount.
Therefore, the present embodiment can make aircraft all steadily can reach rotating speed of target value rapidly when motor speed is greater than or less than rotating speed of target, the control command making the rotating speed of motor can be good at real-time following controller to send, control effects is good, also makes aircraft can obtain good flight stability and mobility.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection range of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection range of the present utility model.
