摘　　要：为弥补永磁直线同步电机运行过程中系统鲁棒性不强、抖动大的缺陷,开发基于DSP的永磁直线同步电机控制系统.该系统以模糊滑模变结构控制为主要控制策略,以TMS320F2812型DSP芯片为主要控制芯片,以IPM智能功率模块、光栅尺和传感器为主要硬件基础,以永磁直线同步电机为主要控制对象.所采用的模糊滑模变结构控制可以有效提高系统响应速度,鲁棒性强,且通过模糊控制可以对滑模变结构控制所产生的抖振现象加以抑制.试验结果表明,该伺服系统鲁棒性强,抖振现象不明显.A system for permanent magnet linear synchronous motor control based on DSP is developed in order to overcome the defect that the system is not robust and the jitter is large in the operation of the permanent magnet linear synchronous motor. The main control strategy of the system is based on fuzzy sliding mode variable structure control, using TMS320F2812 DSP chip as the main control chip, IPM intelligent power module, grating and sensor as the basis for the main hardware, and permanent magnet linear synchronous motor as the main control object. The fuzzy sliding mode variable structure control used in this system can effectively improve the response speed and robustness. The chattering phenomenon of the sliding mode variable structure control can be suppressed by fuzzy control. The experimental results show that the servo system has strong robustness, and the chattering phenomenon is not obvious.
