| 摘 要： | 研究了基于滑模观测器来实现无刷直流电动机的无位置传感器控制的理论方法,由滑模观测器观测电机的反电动势信息,然后估算出电机的转速以及换相信号,由转速估算值和测得的母线电流控制Buck电路占空比构成双闭环调节。同时通过趋近律和低通滤波器削弱了滑模抖振对系统的影响。最后利用MATLAB/Simulink对该控制方法进行仿真研究,仿真结果表明该系统设计合理,并具有一定的鲁棒性。

| Abstract: | A sliding Mode observer of the trapezoidal back EMF was proposed to realize the control of high-speed brushless direct current motor(BLDCM) with no position sensor.The trapezoidal back EMF was used to estimate the speed and the commutation points of the BLDCM,A double closed loop was composed by estimating the speed and current of generatris to adjust the system.The low pass filter and reaching law method are used for chatting reduction of sliding mode.This control method was validated by MATLAB/Simulink.Si... |
