Small unmanned helicopter longitudinal control PID parameter optimization based on genetic algorithm

The PID control as a popularly control method that is used in the control system, this control method is still adopted in many practical applications of the process currently. The paper mainly discusses the classical PID tuning methods, and on the basis of the method, which achieve a small unmanned helicopter longitudinal PID control parameters optimization by introducing the idea of genetic algorithm. The performance of control system is assured when adopting genetic algorithms. The simulation results comparing with the classical PID tuning methods shows that PID controller that is designed with genetic algorithms is better flexibility, and can obtain the better control effect.
