永磁同步电机伺服系统的模糊控制

摘要

In order to overcome the parameter uncertainties, enhance the fast tracking performance of permanent magnet synchronous motor (PMSM) servo system, a self-tuning fuzzy controller is proposed in this paper. It compares with conventional linear PID, the self-tuning fuzzy controller is computing on-line easily and can reduce stability error. Moreover, the controller proposed in this paper has been applied to PMSM servo system, and advantages of the controller have been demonstrated.%为了克服参数的不确定性,提高永磁同步电机伺服系统的快速跟踪能力,文中提出了一种自校正模糊控制器.该自校正模糊控制器与传统控制器相比,具有在线计算简单、减小稳态误差的优点.同时将其应用于永磁同步电机伺服系统的速度控制,证明了该模糊控制器的优越性.
