摘要 论述了综合运用非线性动态逆、自适应模糊系统和滑模控制的优点进行飞行控制律设计的方法。运用非线性动态逆理论对非线性系统进行近似线性化 ,用模糊自适应系统来抵消近似非线性逆带来的误差 ,最终的残差由滑模控制项补偿。根据李亚普诺夫稳定性理论推导了自适应系统权值的调整规律 ,从而保证了闭环系统的稳定性。将此方法应用于带推力矢量飞机重构飞行控制 ,对两类故障的仿真结果表明 :即使系统未检测到故障 ,在较大的舵面损伤情况下 。 The design of the flight controller that exploits the advantages of the nonlinear dynamic inversion, adaptive fuzzy system and slide model control is discussed. First,the nonlinear dynamic inversion theory is used to approximately linearize the nonlinear system. Then an adaptive fuzzy system is adopted to cancel the errors brought with approximate inversion, and the residual error is solved by slide model control. The weight adjustment law is got based on Lyapunov theory to assure the stability of the control system. The resulting control law is applied to the reconfigurable flight controller of an aircraft with vectored thrust. Simulation results show this control law achieves a high level performance even if the aircraft has large undetected failures.
