摘　　要：利用H∞控制理论设计飞机纵向着舰导引系统时,主要问题是控制器阶数过高,机载计算机难以承受。采用基于稳定准则的加性降阶法,设计了某型飞机纵向着舰导引系统H∞降阶控制器。仿真结果表明,所设计的降阶控制器可完全满足着舰系统对抗扰和精确跟踪的要求。The main problem encountered in H∞ controller design of longitudinal automatic carrier landing system is that the air-borne computer cannot afford the computational burden due to the high controller order. In this paper, a reduced-order H∞controller is designed by using balanced truncation method. Simulation results indicate that the reduced-order controller can meet the disturbance attenuation and tracking precision requirements.
