An ADRC flight controller design method based on PSO algorithm is proposed in this paper. The ADRC has strong robustness and fitness for the change of model parameter. In order to improve the flight control performance, an ADRC fight controller is designed. There are many controller parameters in the designed controller, so PSO algorithm is used to optimize the parameters. The simulation results show that the controller optimized by the PSO algorithm has excellent control performance and the design efficiency is improved.
