摘　　要：定量反馈理论(QFT)是一种频域鲁棒控制系统设计方法,综合考虑了对象的不确定范围和对系统的性能指标要求,从而保证了设计结果具有稳定鲁棒性和性能鲁棒性。文中以某飞机的协调转弯模态为例,采用QFT方法设计控制器。仿真结果表明用该控制方法设计的控制器具有良好的鲁棒性。The quantitative feedback theory,a frequency-domain robust control design method,considers synthetically the scope of the plant's uncertainty and performance requirements to the system.So it can guarantee that the designed system has stability robustness and performance robustness.In this paper,the QFT method is used to design the controller of a turn coordination control system for an aircraft.The simulation results show that the designed control system based on QFT has a good robustness.

关 键 词：定量反馈理论 协调转弯 飞行控制系统
