An ADRC Flight Controller Design Based on Dragonfly Algorithm
Aiming at the strong coupling,nonlinearity and severe aerodynamic parameter variations under the complex environment of vehicles,an active disturbance rejection controller design method based on the dragonfly algorithm is proposed.Firstly,a mathematical model based on the three-channel powerless reen-try process of vehicles is established.The extended state observer is used to estimate the system state and total disturbance,and then the observed disturbance is compensated.The dragonfly algorithm is employed to op-timize the parameters of the active disturbance rejection controller.Finally,validation is shown through a vehicle simulation of six-degree-of-freedom.The results show that the optimized controller parameters have better control accuracy and maintain good control performance even under significant aerodynamic parame-ter deviations.
