摘    要:针对永磁直线同步电机(PMLSM)永磁体磁链为常数的特点,对其d-q轴模型进行分析,提出了永磁直线同步电机进给系统的动力学方程.结合传统PID控制和模糊控制的优点,根据永磁直线同步电机直接进给系统的非线性和可能的不确定性因素,建立PID参数自调整的推理规则,设计了永磁直线同步电机进给系统的模糊PID控制器.仿真和实验结果表明,模糊PID控制器与传统PID控制器相比具有更好的动态稳定性和跟踪性能,对外界干扰具有较强的鲁棒性.

关 键 词:永磁直线同步电机  模糊PID控制  模糊推理  鲁棒性

Abstract:Considering the characteristic of the magnet flux of permanent magnet linear synchronous motors (PMLSM) to be constant, the dynamic equation of the PMLSM feeding system is obtained by analyzing PMLSM d-q model. A fuzzy PID controller is designed by combined fuzzy control with conventional PID control. Fuzzy inference rule of PID parameters is designed according to nonlinear and uncertainty of the PMLSM feeding system. Simulation and experiment results show that the fuzzy PID controller is superior to the conventional PID controller in dynamic stability performance and speed tracking power, and the fuzzy PID controller has strong robustness to external disturbance.
Keywords:PMLSM  fuzzy PID control  fuzzy logical inference  robustness
