| 摘 要： | 针对不确定离散时间系统,提出了一种基于扰动补偿趋近律的准滑模控制方法.该方法不仅能够加快系统趋近模态的趋近速度,缩短到达时间,而且能够缩窄系统的准滑动模态带宽,增强系统鲁棒性,有效改善系统动态品质,并无控制抖振和稳态抖振产生.仿真结果表明了该方法的有效性.

| Abstract: | A quasi-sliding-mode control strategy based on disturbance compensation for uncertain discrete-time systems is considered. This new method increases the speed in reaching the destination mode, thus reducing the reaching time. It
also decreases the region of quasi-sliding-mode, thus increasing the robustness and improving the dynamic quality. The undesired control-chattering and steady-states-chattering are avoided. Simulation results show the effectiveness of the proposed method. |
