英文摘要 | Control reconfiguration of flight control system for a large civil aircraft is a difficult problem because of its control surface redundancy and different flight modes. To solve the problem of a jammed surface fault, a sliding mode reconfigurable controller is proposed. Firstly the dynamics model and faults model of the aircraft are established. Secondly, a sliding mode reconfigurable controller is designed to stabilize the flight control system. Finally, to improve reconfiguration performance, a Sliding Mode Controller with fixed-point iteration Control Allocation scheme (SMCCA) is proposed to achieve better tracking performance and optimal control surface distribution under the fault circumstance. Simulation results of the Boeing747 model with elevator faults show that the SMCCA algorithm has better performances in robust stability and command tracking than those in LQR and SMC. |
