摘要
舰载机着舰对控制系统的鲁棒性能等要求很高,同时极点位置对着舰飞行品质具有重要影响。现将极点配置和鲁棒控制相结合,研究了含区域极点配置的舰载机着舰H_2/H_∞控制。结果显示系统在极点配置、高度偏差纠正、舰尾流抑制、模型摄动抑制、操纵面响应等方面的控制效果很好,达到着舰规范要求,远优于工程上自动着舰控制结构。着舰阻力曲线反区效应和升降舵直接力效应,会让舰载机动力学有两个非最小相位零点,自动着舰工程上的控制结构只能消除反区效应带来的正零点,而含区域极点配置的H_2/H_∞控制能彻底地能解决非最小相位的问题。
The requirement in the robust performance of aircraft carrier landing control system is very high. And poles have an important influence on the performance of landing flying qualities too. So robust control was eonbined with Pole - placement to research cartier landing control ultilizing H2/H∞ control with regional pole - placement. The results show that poles are assigned in ideal place, and landing control effect is very good at heigh rectification, air wake suppression, and model perturbation suppression, control surface and so on, which is better than the carrier landing engineering control structure. Engineering control method can only eliminate the positive point caused by drag curve backside area, but H2/H∞ control with regional pole - placement can solve non - minimum phase problem downright.
