基于滑模变结构的开关磁阻电机角度控制

Angle Control of Switched Reluctance Motor based on Sliding Mode Variable Structure

针对开关磁阻电机(SRM)常规线性方法控制效果不理想以及高速运转时以相电压作为控制量的不合理性的问题,在分析开关磁阻电机开通、关断角对输出转矩的作用以及SRM数学模型的基础上,提出了基速以上时以关断角作为控制量的滑模变结构角度控制方法,并基于此方法设计了实验系统,实验结果表明:该系统具有良好的动静态性能,具有较强的鲁棒性。

In view of the fact that control effect of Switched Reluctance Motor （SRM） by using normal linear method is not ideal, and the fact that considering the phrase voltage as the control value when the rotation speed is very high is unreasonable, on the basis of contribution of the turn-on and turn-off angle to the output torque and of the mathematical model of SRM, this paper put forward a control method taking the turn-off angle as the control value when the SRM rotation speed is above the base speed, designed an experimental system, whose experiment results show that： this system has good dynamic and static performance and has strong robustness.
