The Optimization of Flight Control System Based on an Improved Evolutionary Strategy and Referenced Model

The performance and flying quality of the aircraft depend on its flight control system (FCS), and the parameters of the FCS are very difficult to set because the aircraft is a time-varying system and the monotone changing laws of the parameters are required. In this paper, an optimizing method of the parameter of FCS, which is based on an improved evolutionary strategy and referenced model, is proposed. In this method the requirement on the parameter and the flying quality are considered. To validate the effect of this method, a simulation of a kind of aircraft, which covers a big flying envelope, is made. The result shows that parameters gotten by the given fast method are satisfied.
