位置与速度单环结构下永磁同步电机伺服系统改进有限时间复合控制器设计

The conventional position servo system usually adopts the position-speed-current three closed-loop control structure. Although each loop variable can meet the expectation, the bandwidth of the outer loop is restricted by the inner loop, which affects the dynamic performance of the outer loop. In this article, a finite-time position-speed single-loop controller was designed to improve the position ...
