基于干扰观测器的新一代歼击机鲁棒飞行逆控制器设计

基于干扰观测器设计了新一代歼击机的鲁棒飞行逆控制器。根据时标分离的原则，将机动飞机分为快慢不同的回路。采用动态逆方法设计了快回路和慢回路控制器，并在慢回路用干扰观测器估计飞机所受的扰动，同时，用于在线补偿动态逆误差。仿真结果表明，该设计合理。

Design of Robust Flight Inversion Controller for the New Generation Fighter Based on Disturbance Observer

A discussion is devoted to the design of a robust flight inversion controller for the new generation fighter based on disturbance observer in this paper. According to the time scale separation principle, the flight system is divided into two subsystems,a quick loop and a slow loop. The dynamic inversion controllers are designed for the quick loop and the slow loop. The disturbance observer is used to approximate the disturbance of the fighter and to on-line compensate the model inversion error. Finally, the simulation results demonstrate the availabilityof the designed robust flight controller.
