| 摘 要： | 针对受正弦信号干扰的不确定离散时间系统,提出一种基于死区离散趋近律的准滑模控制方法. 系统能够由任一初始状态向死区作单调趋近运动,并于有限时间到达准滑动模态区作准滑动模态运动. 准滑动模态带具有任意阶次小的特点.该方法进一步增强了系统鲁棒性,有效改善系统动态品质,减小了稳态误差.系统无 控制抖振和稳态抖振产生.仿真结果表明该方法的有效性.

| Abstract: | A quasi-sliding-mode control design method based on discrete reaching law with dead zone is considered for discrete time systems with uncertainty which is a sinusoidal signal. The control strategy could drive the state of controlled system to the dead zone monotonously for arbitrary initial value and the quasi-sliding-mode is reached in a finite time. Quasi-sliding- mode band could be designed to be as small as arbitrary order of magnitude. At the same time, better robustness is guaranteed, dynamic quality ... |
