摘要
针对传统PI控制器无法满足非线性、参数时变、负载扰动的永磁同步电机高性能速度控制要求,分别设计了模糊PI速度控制器,模糊电流及模糊前馈控制器,并应用到永磁同步电机矢量控制调速系统中。控制系统有效地克服了电机运行过程中内外部参数变化对电机转速、电流的影响,并能有效地补偿负载扰动。在MATLAB环境下构建模型进行仿真验证,结果表明,新型的复合控制方法改善了转矩和电流波形,可以有效补偿负载扰动,具有较好的动静态性能和鲁棒性。
In order to solve the problems that traditional PI controller can not meet the nonlinearity, time-varying parameters, load disturbance performance permanent magnet synchronous motor high speed control system＇ s require- ments, a fuzzy PI speed controller, two fuzzy currents and a fuzzy feed-forward controller were designed and applied in the vector control of permanent magnet synchronous motor speed control system. The control system effectively o- vercame the internal and external parameters changes that influence the motor speed and current, and can effectively compensate the load disturbance. This new .type composite control system was built using MATLAB. The simulation results show that the method can improve the torque and current waveforms, compensate the load disturbance and have good dynamic and static performance and robustness.
