应用高速无刷直流电机换相滞后角软件补偿方法的控制系统 Application of high-speed brushless DC motor commutation control system software lag angle compensation method

技术领域 FIELD

[0001]本发明属于无刷直流电机控制领域,具体涉及一种应用高速无刷直流电机换相滞后角软件补偿方法的控制系统。 [0001] The present invention belongs to the field of brushless DC motor control, particularly relates to a control system for application of high speed brushless DC motor commutation retarded angle software compensation method.

背景技术 Background technique

[0002]高速无刷直流电机采用Buck(直流降压)变换器加三相逆变桥的方式进行驱动,其换相时刻由位置信号决定,位置信号是通过三个霍尔传感器得到的,由于霍尔传感器受到电机磁场、RC滤波器以及安装位置偏差等影响,其发出的换相信号滞后于真实的换相信号,存在一定的滞后角度。 [0002] High speed brushless DC motor using the Buck (step-down DC) was added a three-phase inverter bridge driving transformer which commutation timing is determined by the position signal, the position signal is obtained by the three Hall sensors, since Hall sensor magnetic field by the motor, an RC filter and a mounting impact positional deviation, for which lags the phase signal emitted commutation real number, there is a certain lag angle. 当电机工作在高速时,该换相滞后角会引起直流电机非导通相绕组出现较大续流,导通相绕组在关断前出现较大的电流尖峰,导致电机相电流波形发生畸变,电机发热量增加,温度升高,从而产生额外的电机损耗。 When the motor operates at high speed, the retarded angle commutation causes the non-conduction phase DC motor winding to a larger freewheel, a larger conduction phase winding is turned off before the current spikes, resulting in the motor phase current waveform distortion, motor heat, increased temperature, thereby generating additional motor losses.

发明内容 SUMMARY

[0003]本发明是为了克服现有技术中存在的缺点而提出的,其目的是提供一种应用高速无刷直流电机换相滞后角软件补偿方法的控制系统。 [0003] The present invention is to overcome the disadvantages of the prior art proposed in the present, which application object to provide a high-speed brushless DC motor commutation control system software lag angle compensation method.

[0005]滞后角由中断延迟滞后角、安装误差角、RC滤波滞后角三部分组成,其中中断延迟、霍尔传感器安装误差都是静态误差,可以通过测量获得,霍尔信号经RC滤波器产生的动态误差则通过计算获得。 [0005] from the retarded angle retarded angle interrupt latency, installation error angle, the retarded angle RC filter composed of three parts, wherein the interrupt latency, the Hall sensor mounting errors are static errors, may be obtained by measuring the signal generated by the Hall RC filter the dynamic error is obtained by calculation.

[0006]无刷直流电机以霍尔信号为中断触发信号,按照一定的顺序,每60°电角度(一个换相周期为60°电角度)进行一次换相,由于中断服务程序只能进行中断延时,不能进行中断超前。 [0006] In the brushless DC motor Hall signal as a trigger signal an interrupt, in a certain order, every electrical angle of 60 ° (a commutation cycle of electrical angle 60 °) for a commutation, since only interrupt the interrupt service routine delay can not be interrupted ahead. 为了实现滞后角补偿,必须先根据电机的实时转速计算出60°电角度对应的换相周期,再将换相顺序提前60°电角度(一个换相周期),然后在中断程序中,通过定时程序推迟60°电角度减去滞后角后对应的时间,再进行换相,这样便将换相时刻提前了一定的滞后角,实现了滞后角补偿的目的。 To achieve the lag angle compensation, must be calculated according to the real speed of the motor commutation period corresponding to the electrical angle 60 °, then the commutation sequence of electric angle 60 ° ahead of (a commutation period), then in the interrupt program, through the timing program subtracts the delayed 60 ° in electrical angle corresponding to the angle of lag time, then the commutation, the commutation timing advance so that it puts a certain lag angle, to achieve the purpose of the lag angle compensation.
