摘要: 针对满足一定条件的一类不确定部分上界不确知的系统,提出了一种参数自适应积分滑模控制策略。通过在切换函数中引入跟踪误差积分项,消除了传统滑模变结构控制需要被跟踪信号导数已知的假设。同时基于Lyapunov方法引入参数自适应律,使系统能够抑制干扰。采用该控制方法,进行大椭圆轨道慢旋目标同步绕飞跟踪控制器设计。仿真结果表明,该方法具有较强的鲁棒性以及良好的跟踪性能。

Abstract: This paper presents an integral sliding mode control with adaptive parameters for a class of systems satisfying some conditions when the upper bounds of uncertainties are unknown. The switching function includes the integral of tracking error to avoid assuming that the derivative of desired signal must be known in conventional sliding mode variable structure control. This control approach uses the parameter adaptive algorithm based on the Lyapunov method to make the system reject disturbances. The proposed method is applied to slowly rotating non-cooperative target in an arbitrary elliptical orbit synchronous fly-around position tracking control. Simulation results indicate that the control approach is robust and improves the tracking accuracy considerably.

Key words: slowly rotating target, elliptical orbit, integral sliding mode control, adaptive control
