摘要
针对永磁同步电机非线性、多变量、强耦合与参数时变易干扰的特点,将模糊控制器应用于矢量控制系统,提出了一种基于模糊理论PI控制器,利用模糊控制对PI控制器中的参数在线调整,使得模糊PI控制器同时具有模糊控制灵活性强和PI控制精度高的优点,从而达到最优控制。在MATLAB/SIMULINK环境中对系统进行了仿真研究,结果表明模糊控制器较普通控制器具有更快的响应速度,更小的超调量以及更强的鲁棒性,能够有效改善系统的动静态性能。
According to the nonlinear,permanent magnet synchronous motor is multivariable,strong coupling and interference characteristics of variation of parameters,the fuzzy controller is applied to the vector control system,this paper proposes a fuzzy controller based on PI theory,we use fuzzy control to adjust the parameter of the PI controller,the fuzzy PI controller and fuzzy control has the advantages of flexibility and PI high control precision,so as to achieve optimal control.The simulation study of the system in the MATLAB/SIMULINK environment,the results show that the fuzzy controller is the common controller has faster response speed,smaller overshoot and stronger robustness,can effectively improve the dynamic and static performance.
