基于H∞控制的某空空导弹俯偏回路设计

针对某导弹飞行空域广、参数摄动大、鲁棒性强等控制特点,采用H∞控制的混合灵敏度和线性二次调节（LQR）设计了自动驾驶仪俯偏回路。其中,内回路采用LQR限定模型的不确定性界,外回路用H∞控制混合灵敏度设计控制器。仿真结果表明：所设计的自动驾驶仪可较好地抑制参数摄动,鲁棒性较佳。

A Study on H∞ Control Theory Applied in Some Missile P/Y Channel

According to the characteristics of the extensive airspace of flying, the aerodynamic parameters pertubing in large range and the powerful robustness of some air-to-air missile, the method of mixed sensitivity of H∞ control theory and linear quarter regulation （LQR） was applied to the design of the pitching and yaw channel for the autopoilot of the missile in this paper. The LQR was used to limit the uncertainness margin of the model in the inner loop, and the standard H∞ mixed sensitivity was used to design the controller in the outer loop. The numeric simulation results showed that the parameter disturbing could be restrained by the designed autopoilot, which robustness was good.
