针对存在干扰、输入约束和状态约束的再入飞行器，提出了一种面向控制性能的三环控制方案。该控制方案的具体结构是内环中设计了一种自适应滑模控制方法，以保证系统能够有效跟踪在线规划的最优参考模型；外环在考虑系统不确定性，且不违反控制约束和状态约束的前提下，利用在线优化算法，设计一种动态性能最优的参考模型；中环设计了一种干扰边界估计算法，以对外环在线规划最优参考模型时提供辅助手段。经过仿真验证，所提出的三环控制方案不仅能够保证系统具有很好的稳态性能，而且能够保证系统具有快速收敛的动态性能。

A performance oriented three?loop control scheme is proposed, under the input and state constraints. The specific structure of the control scheme is that, an adaptive sliding mode controller is designed in the inner loop which is used to track the reference model replanted online, and the reference model is designed in the outer loop through using online optimization algorithm, in which the uncertainty and the state constraints are well considered. The bound of the disturbance is estimated in the middle loop, and is used in the design process of the reference model. The three loop controller can not only insure a steady performance, but al?so insure a fast convergence of dynamic performance. And the efficacy of the method is demonstrated through simulation.
