一种改进的变结构控制器在转台中的应用

针对变结构控制的抖振问题,本提出了一种新的解决方案,采用多切换面的改进变结构控制,在保证了理想滑动模态的抗干扰能力强、鲁棒性好的优点的同时,很好的削弱了系统抖振。仿真结果表明,这种控制规律应用在转台上取得了良好的控制效果。

Application of a Modified Variable Structure Controller in Test Tables

In view of the chattering existed in variable structure control,a new method,which is based on multiple sliding surfaces,is put forward to resolve this problem.This control law not only retains the merits of ideal sliding modes, such as good interference rejection and robustness, but also alleviates system chattering in a great deal.The simulation results demonstrate that this control law achieves good performance in test tables.
