摘要
通过对永磁同步电机的数学模型的分析,结合矢量控制原理,建立永磁同步电机矢量控制调速系统仿真模型,针对被控对象的的非线性,强耦合,参数时变等特性,引进模糊控制策略,并设计模糊自适应PID控制器应用其中,以验证控制方法的有效性。仿真结果表明,与传统PID相比,模糊PID具有响应速度快,超调量小,抗扰能力和鲁棒性强等优点,能够更好的提高永磁同步电机的调速性能。
The permanent magnet synchronous motor speed control system simulation model was established by the analysis of the mathematical model of the permanent magnet synchronous motor,combined with the vector control principle.The fuzzy control strategy was introduced and the design of fuzzy adaptive PID controller was applied,considering that the controlled object was nonlinear,strong coupling,parameters time-varying characteristics,to verify the effectiveness of the control method.The simulation results show that fuzzy PID had a fast response,small overshoot,and anti-interference ability and robustness,compared with traditional PID,and improved the speed performance of permanent magnet synchronous motor.
