研究了应用混合灵敏度H∞控制理论设计飞行控制系统鲁棒控制器的问题,分析并提出了利用粒子群优化算法来优化H∞加权函数阵,找到了同时满足系统时域和频域性能要求的鲁棒控制器。以某型推力矢量飞机侧向运动为例进行仿真与设计。仿真结果表明,所设计出来的飞行控制系统不仅具有良好的鲁棒稳定性,还具有很好的鲁棒性能。

Robust controller design for flight control system based on H∞ control theory is mainly studied in this paper. Particle swarm optimization is used to optimize the weighting functions are presented, so the H∞ controller meets the time and frequency domain indexes. The design of H∞ control and digital simulation for a lateral motion of a thrust vector aircraft are given. The simulation results show that the system not only has stability robustness, but also satisfies some performance constrains.
