Design of Robust Controller Based on Adaptive Backstepping and Slide Mode for Flight Simulator

摘要

Considering unknown nonlinearities, external disturbances and parameter perturbations existing in the flight simulator, A backstepping and slide mode controller is designed for the flight simulator. Firstly, the dynamic model of the flight simulator is proposed by test. Secondly, the backstepping controller with friction parameter update law is deduced for this dynamic model. Finally, simulation results show that the output from the system can achieve asymptotic tracking of the given position reference signal and the aberration of velocity response under the control of common PID controller is overcome.
