Unmanned Helicopter Course PID Controller Parameters Setting and Simulation

Article Preview

Abstract:

In the basis of the rolling angle inside loop controller stability, this paper using genetic algorithm to optimize the parameters of PID, in order to get the flight course outside loop controller parameters constituted by course angle feedback signal. Aiming at the small unmanned helicopter course stability control model features, we choose the rise time of system, the steady-state error and proportion of combination as an optimum target function. To ensure the effect of the controller and reduce the system shock, we introduce system shock times and multiply punishment function. It has better flexibility, adaptability, stability and can guaranty the system controller effect and improves the system capability by adopting the genetic algorithm to develop the PID controller. The simulation results verify the effectiveness of the method that we put forward.
