Abstract:

The tuning of PID parameter of the Four-rotor by trial and error method suffers low accuracy and unstable performance.The global artificial fish swarm algorithm is applied to search the optimal solution in the global scope by preying,following,swarming,etc.The principles of the artificial fish swarm algorithm and PID algorithm are introduced.The application in the Four-rotor unmanned aerial vehicles control system of the algorithm is described in detail.Simulation results show that the controller has better response,adaptability and robustness.

Key words: four rotor;flight control;PID algorithm;artificial fish swarm algorithm
