| Abstract: | The aircraft-pilot closed loop system which is constituted by an aircraft with fly-by-wire flight control system is a high order nonlinear system.Regarding the stability of aircraft-pilot system with fly-by-wire flight control system,this paper proposes a method of using the Genetic Algorithm(GA) to make equivalent matching of the aircraft-pilot system in frequency domain,then studying on the stability of lower order system by the root locus method.Simulation results show that this initial value choosing pr... |
