Model Reference Sliding Mode Controller Design for Reconfigurable Flight Control

摘要

Based on the model reference control, a sliding mode controller is proposed for the reconfigurable flight control system in this paper. Using this controller, the controlled plant can track the reference model precisely. It is shown that this method provides better performance for the flight control system. Firstly, a Proportional-Integral type sliding surface is designed through Linear- Quadratic Regulator method to make the sliding mode have good dynamic characteristics and to eliminate the steady state error. Secondly, the simple saturating control is adopted to avoid the chattering phenomena. The simulation results show that the flight control system with this controller not only doesn't require the procedure of fault detection and isolation, but also achieves the model tracking control.
