电流滞环跟踪的双闭环调速系统仿真设计
|
摘要
为提高抗干扰能力和改善动态性能,设计了双闭环调速系统。采用由电流滞环和转速外环构成的感应电动机双闭环控制,以进一步提高动态特性。当1.5 s时,负载由15 N·m变为30 N·m,转速仍维持恒定的1 400 r/min,同时加强磁链控制,构建了基于动态模型的异步电动机的多重闭环控制的调速系统。实验结果表明,该系统动态性能更好,磁链轨迹更接近于圆。
In order to improve the anti-jamming capability and improve the dynamic performance,current hysteresis and speed outer ring composed of induction motor double closed-loop control are used to further improve the motor dynamic characteristics and anti-interference ability. When the load of 1. 5 s was changed from 15 N·m to 30 N·m,the speed remained constant at 1 400 r/min,and can strengthen the flux linkage control.We construct the multiple closed-loop control based on dynamic model of the asynchronous motor speed control system. It is concluded that by using this control method the motor dynamic performance is better,and flux linkage locus is more close to round.
