Aircraft flight control using method of robustness aimed at uncertainty

Abstract

Method of μ synthesis based on self-contained structured singular value theory provides a resolution for control system with uncertain character. It makes the control system to have enough robustness and optimal control performance. When the aircraft is flying in the dense aerosphere, the autopilot of the aircraft is facing such a control system with a lot of uncertain elements. To obtain the optimal robustness in such case, the method of μ synthesis is used to design the autopilot in this paper. Also the result of simulation is tested and analysed. And the final analysis indicates the adopted controller has an effective result to the uncertainty.
