基于无源性的感应电机调速系统的建模与仿真

Modeling and Simulation of Induction Motor Speed Control Systems Based on Passivity

利用电机转子磁链子系统的无源性,给出带电流内环速度控制系统的一种简明设计,以达到控制感应电机速度之目的。所设计的系统无须转子磁链反馈即能稳定跟踪转子磁链的参考值。仿真结果显示:对速度给定值有着良好的跟踪,且对转子电阻呈现鲁棒性。

To proceed with induction motor speed control task, by using the passivity of motor rotor flux subsystems, a clear and simple design for the speed control systems with inner current-loops is presented. The system designed stably tracks the reference rotor flux without rotor flux feedback. The emulating result also shows the good characteristic to track the reference speed, and the robustness with regard to the rotor resistance.
