Abstract

This article presents the equation of motion for the aircraft in the turbulence. Based on these equations, a trajectory tracking controller is designed using the nonlinear dynamic inverse. In order to reject the disturbance influence, the nonlinear disturbance observer is compensated for the design of the trajectory tracking controller. Simulation results show that the trajectory tracking controller with the nonlinear disturbance observer has a better control performance.
