针对一类单输入单输出的离散时间系统,提出了一种基于快速输出采样反馈技术(FOS)的无抖振滑模控制器.该控制策略避免了在控制器中采用切换模式,从而消除了切换面附近的抖振.理论分析和仿真结果表明该方法不仅能保证闭环系统的稳定性,而且能提高系统的稳态精度.
For a class of discrete-time systems with single-input and single-output, a chattering-free sliding mode controller based on fast output sampling feedback (FOS) is proposed, which avoids switching modes in the controller and eliminates The chattering near the switching surface is analyzed theoretically and the simulation results show that this method can not only ensure the stability of the closed-loop system but also improve the steady-state accuracy of the system.
