Four Rotor Aircraft the Simulation Research of Automatic Control

Four rotor aircraft control system is a multivariable,nonlinear and strong coupling system. Traditional control algorithm for four rotor aircraft has low control precision and slow dynamic response. This paper presents a kind of automatic four rotor aircraft control method based on improved genetic algorithm. Firstly,four rotor aircraft control model is established,and the optimal target function is obtained by using improved genetic algorithm. Secondly,the mutation probability and crossover probability in the genetic algorithm are improved,which can automatically adapt to the changing parameters in the process of control,the fitness of each individual is calculated,and the best fitness of the individual is obtained. Finally,the optimal control parameters are obtained. Experimental results show that the improved algorithm can improve the control accuracy and response speed.
