摘要
利用Lyapunov稳定性理论研究了一类广义双线性系统的镇定问题.通过构造特殊的二阶终端滑模超曲面,设计相应的变结构控制器,使闭环系统在有限时间内实现滑动模运动,系统的状态在平衡点渐近稳定.该设计方法能有效削弱系统的高频抖振.仿真结果验证了设计方法的可行性.
Lyapunov stability theory is employed to investigate the stabilization problems in a class of singular bilinear systems.A special second-order terminal sliding mode hyper-surface is constructed and the corresponding variable structure controller is designed to make the sliding mode move in finite time and to guarantee the closed-loop systems to be asymptotically stable.The high frequency chattering of the control signals in the class of singular bilinear systems is reduced by using the method designed.Simulation results show the feasibility of the designed approach.
