摘要 针对开关磁阻电机采用传统控制方法存在转矩脉动大、调速系统性能低的缺点,本文提出了直接瞬时转矩控制(DITC)与模糊自适应PID控制器结合的新方法。通过瞬时转矩闭环控制抑制转矩脉动,应用模糊理论根据电机运行情况在线自调节PID的参数改善系统调速性能。仿真结果表明,DITC控制方法对转矩脉动的抑制效果明显优于传统PWM控制和直接转矩控制方法,模糊自适应PID控制器的引入又能使调速系统具有超调小、转速稳定时间短、鲁棒性强的优点。

Abstract:For Switched Reluctance Motor using traditional control methods existing disadvantages of large torque ripple and poor speed control performance, this paper describes a new approach of combining direct instantaneous torque control(DITC) with fuzzy adaptive PID controller. Closed loop control of instantaneous torque is used to restrain torque ripple and fuzzy theory is used to adjust PID parameters online according to the motor’s running condition to improve the system’s speed control performance. The simulation result shows that the inhibitory effect of direct instantaneous torque control method on torque ripple is superior to traditional PWM control and direct torque control, and the introduction of fuzzy adaptive PID controller can enable the speed control system to have advantages of small overshoot, short speed recovery time and strong robustness.
