研究具有自主知识产权的高性能交流伺服控制技术,尤其是针对具有广阔应用前景的永磁同步电动机的伺服控制技术,具有重大的理论意义和经济利益。在分析永磁同步电机的近似动态结构的基础上,分别对电流环控制器、速度环控制器、位置控制器进行设计。电流环采用常规的PI控制器,速度环采用基于遗传算法的参数自整定PI控制器,位置环采用简单的P控制器。针对选用的三相Y型连接永磁同步电机求得控制参数。应用该设计策略进行永磁同步电机数学模型的设计,可以实现对同步电机的稳定控制。
Research on high performance AC servo control technology with independent intellectual property rights, especially for the servo control technology of permanent magnet synchronous motor with broad application prospects, has great theoretical significance and economic benefits. On the basis of analyzing the approximate dynamic structure of permanent magnet synchronous motor, the current loop controller, speed loop controller and position controller are respectively designed. The current loop adopts the conventional PI controller, the speed loop adopts the parameter self-tuning PI controller based on genetic algorithm, and the position loop uses the simple P controller. For the selected three-phase Y-connected permanent magnet synchronous motor control parameters. Applying this design strategy to design the mathematical model of permanent magnet synchronous motor can realize the stable control of the synchronous motor.
