摘要
介绍了自激换流低速磁阻电动机的结构及换流原理;提出了该种电机的基于SPWM和SVPWM变频调速的控制方案;在M ATLAB下建立了电机控制系统的仿真模型。通过仿真试验,比较了各控制方案,提出电机的超前导通角概念,从时间上补偿空间负载角,有效减少了输出电流,从而为该种电机系统的设计与控制提出了新思路。
This paper presents two different variable frequency speed control strategies for self-commutating low speed reluctance motor （SCLRM）using SPWM and SVPWM, respectively, based on the introduction of the principle and construction of this kind of motor. The simulation models of the two control systems are built with MATLAB/SIMULINK. Besides,the concept of commutation-advance angle is proposed for,which acts as the time load angle adding to the space load angle for a certain current so as to increase the torque output. The simulation results are presented with analysis.
