Abstract :
It is difficult to establish accurate models for complex flight control systems, but neural network has arbitrary nonlinear approximation ability. In order to overcome modeling errors and disturbances, a method of hybrid flight control is proposed. Firstly, inverse model of the object is identified online through neural networks and the feedback linearization control system is reached. And then circle theorem is used to design linear robust controller to control the state variables follow the input. A dynamic longitudinal model of a high-performance aircraft is considered to demonstrate the effectiveness of the proposed control scheme. Simulation results show designed controllers are highly adaptive and anti-interference ability.
