【摘要】 本文提出了一种交流永磁同步电机伺服系统的变结构加速度控制法。通过对变结构系统进行加速度控制，可以大大削弱变结构控制产生的抖动，提高运行的平稳性和定位精度，减少能耗。理论分析和实验结果表明，本方法解决了变结构控制在原点附近和恒速运行区段中的抖动问题，而且结构简单，按照精度要求可方便地调节控制参数。更多还原

【Abstract】 A method of permanent magnet synchronous motor ac servo system with variable structure acceleration control is proposed. By means of variable structure acceleration control, the chattering produced by variable structure control is greatly alleviated. Operating smothness, steadiness and positioning precision are improved and energy loss is saved. The theoretical analysis and experiment results show that this method not only solves the problem of chattering on original area and other running section, but also is simple in structure. Control parameters can be conveniently adjusted in accordance with precision required.更多还原
