外部干扰与状态约束下卫星姿态系统预设性能跟踪控制
Prescribed performance tracking control for a satellite attitude control system under external disturbances and state constraints
摘要
Abstract
Objectives To achieve accurate tracking of reference trajectories,this study investigates the atti-tude tracking control problem for a satellite attitude control system subject to external disturbances,perfor-mance constraints,and state constraints.Methods A prescribed performance anti-disturbance control scheme is proposed based on improved prescribed performance control(PPC),disturbance observer-based control(DOBC),and barrier Lyapunov function(BLF)techniques.First,a finite-time performance func-tion with a slow-fast-slow convergence characteristic is designed to dynamically adjust convergence rates in different response stages,thereby improving transient and steady-state performance.Second,a prescribed-time disturbance observer(PTDO)based on a time-scale function is developed to ensure that the estimation error converges to a sufficiently small residual set within a predefined time.Third,the BLF method is employed to transform the constrained satellite attitude system into an equivalent unconstrained system,and a prescribed performance anti-disturbance controller is designed using the backstepping method combined with disturbance estimation.Furthermore,Lyapunov stability theory is applied to derive sufficient conditions guaranteeing uniform boundedness of the closed-loop system,and a coordinated design framework for the controller and observer is established.Finally,numerical simulations are conducted to verify the effectiveness of the proposed method.Results Under external disturbances,the PTDO achieves fast and accurate disturbance estimation and compensation within a predefined time.Meanwhile,the pro-posed controller ensures that the satellite attitude control system satisfies asymmetric time-varying state con-straints,and the attitude tracking error converges within a predefined performance bound.Conclusions Simulation results demonstrate that the proposed method enables high-precision attitude tracking control of satellite systems under external disturbances and complex state constraints.关键词
