一种基于系统不确定和干扰有界的准滑模控制

Pseud-sliding Mode Control of Based on System Uncertainty and Disturb Bounded

针对一类非线性系统,基于系统不确定性和干扰均有界的条件下,研究了采用饱和函数的边界层准滑模变结构控制器的设计,边界层外采用常规滑模控制,边界层内采用线性化反馈,并论证了滑动模态的存在和到达条件。最后通过仿真实例证明了所设计的准滑模变结构控制器的有效性,并能削弱一定的抖振。

For a class of nonlinear system,basing on system uncertainty and disturb bounded,boundary layer Pseud-sliding mode controller with saturation function are researched,common sliding mode control inside of boundary layer,linear feedback out- side of boundary layer^and demonstrated the existence and reaching condition.In the last,a simulation example proved ef- fectiveness of the designed controller,and weakened chattering.
