Optimization of the General Aviation Aircraft Longitudinal Controller Parameters Based on Genetic Algorithm
The PID control is a popularly control method that used in control systems, which is still adopted in many practical application processes.This paper is based on the oringinal navigation aircraft longitudinal channels model,and discusses the setting of navigation autopilot longitudinal channels model in the PID controller parameters, using General Aviation Aircraft Longitudinal channels of PID control parameters optimization based on Genetic Algorithm.In contrast with the simulink7.1 simulation results of the longitudinal channel model, base on the thought of genetic algorithm and use MATLAB language program to get the parameters of the controller, adjusting the parameters to achieve the optimization of PID control parameters. The result of SIMULINK simulation: The PID controller which is designed by using the genetic algorithm is more adaptability, flexibility, and can guarantee the system control effect.
