Aircraft Trajectory Control with Feedback Linearization for General Nonlinear Systems

The feedback linearization method is further developed for the controller design on general nonlinear systems. Through the Lyapunov stability theory, the intractable nonlinear implicit algebraic control equations are effectively solved with the dynamic approach, and the asymptotic tracking performance is guaranteed. Moreover, it is proved that the proposed dynamic feedback controller may be used in an inverse-free version to the set-point control. With this method, a nonlinear aircraft outer-loop trajectory controller is developed. For the concern regarding the controller's robustness, the integral control technique is combined to counteract the adverse effect from modeling errors. Simulation results verify the well performance of the proposed controller.
