| 摘 要： | 由于高超声速飞行器飞行过程中存在无法预知的扰动和不确定因素,选用H∞鲁棒控制理论进行控制系统设计。研究了H∞混合灵敏度优化设计方法,选取适当的加权函数,根据＂2-Riccati方程＂利用Matlab鲁棒工具箱设计控制器。仿真结果表明,采用混合灵敏度设计方法设计出的控制器能够满足设计指标的要求,达到很好的控制效果。

| Abstract: | H∞ Robust Control Theory is chosen to design the control system of hypersonic vehicles in fight to overcome unpredictable disturbance and uncertainty.The theory of mixed sensitivity is studied.A suitable weighting matrix is chosen for the controller and it is calculated by Robust Toolbox and ＂2-Riccati equations＂.The results of simulation and analysis show that the controller designed with mixed sensitivity well meet design specifications. |
