Adaptive Multivariable Reentry Attitude Control of RLV With Prescribed Performance
提出一种针对可重复使用运载器的自适应多变量控制算法，利用时变自适应增益和预设性能函数，确保再入姿态跟踪误差在预设区域内，且不依赖扰动上界。
A novel adaptive multivariable control algorithm is proposed for reusable launch vehicle (RLV) subject to bounded but unknown disturbances. In the proposed algorithm, a time-varying nonoverestimated adaptive gain is designed based on the prescribed performance function. The proposed method is very simple and easy implementation, and the Lyapunov-based technique is utilized to guarantee that the reentry attitude tracking errors are confined in some prescribed regions independent of the upper bound of the disturbances. Finally, the efficiency of the developed algorithm is illustrated by simulation results.
