Description
Technical field
The present invention relates to industrial automatic control field, relate in particular to method, device and control system that a kind of brushless electric machine phase advance angle upper limit is set.
Background technology
Brushless motor utilizes electronic commutation to substitute mechanical commutation, overcome the series of problems that traditional direct current machine produces due to brush friction, and have that good speed adjustment features, volume are little, efficiency advantages of higher, thereby be widely used in every field and daily life that national economy produces.
The winding of brushless electric machine is inductance characteristic, and therefore winding current lags behind applied voltage.So certain phase advance angle is set conventionally to make phase current and corresponding back electromotive force homophase, to reach the object that improves motor output torque and efficiency.Arranging of phase advance angle can detect realization by phase current, but need to consume more computational resource, and hardware cost is also high.Therefore often adopt the method for estimation indirectly to carry out the calculating of phase advance angle, such as by detecting bus current and will obtaining phase advance angle after the control parameter computing of itself and motor.Taking the automatic advance angle algorithm based on motor average current as example, phase advance angle is directly proportional to motor average current.
But this automatic advance angle algorithm can cause comparatively distinct issues, it is exactly motor underloading easy driving when especially unloaded.Motor driving is embodied in motor speed and power violent increasing suddenly.This is relevant with the positive feedback of automatic advance angle algorithm, and that is: on the one hand, in the time that motor underloading is especially unloaded, motor is easily subject to external interference and enters weak magnetic; On the other hand, once enter weak magnetic, electric efficiency declines, bus current rises, and advance angle can increase thus, makes motor enter the degree of weak magnetic higher, and this further causes speed and the Current rise of motor.This positive feedback finally causes the rotating speed of motor and power to increase sharply suddenly and is out of control.Adopt fixed lead angle, although can cut off described positive feedback, in the time that adopted advance angle is larger, motor is easy driving also.Motor driving can cause motor overheating and be impaired, even threatens personal security.

A kind of method that the embodiment of the present invention one provides the brushless electric machine phase advance angle upper limit to set, as shown in Figure 1, described in comprise the steps:
Step 110, motor conditions sensed parameter;
Concrete, motor status parameter comprises the rotating speed of motor;
The control module being connected with brushless electric machine detects the operating state of brushless electric machine, thereby obtains the current rotating speed FG of motor.
Step 120, obtains the first control parameter;
Concrete, first controls parameter comprises motor lines voltage Vs.

1time, in advance angle, be limited to U
l1.In the current range limiting, (as be less than I
2scope in), advance angle upper limit U
l1the numerical value of the current phase advance angle of the motor that calculates higher than advance angle algorithm.For example average current is I
1time, the phase advance angle of output is LA
1, LA
1at U
l1scope in, therefore can not limit the phase place of the pumping signal that puts on motor, can not affect the normal operating conditions of motor.
When motor load diminishes as L
2time, the advance angle upper limit can decrease as U
l2.Now, average current I
