Design of Adaptive Backstepping Control for Aircraft Generator Control System

The classical PID control does not consider the external disturbance and uncertain parameters of the system which control accuracy cannot meet the requirements. Based on the mathematical model of three-stage generator, this paper adopts the control algorithm of current inner loop regulation based on exciter model, voltage outer loop regulation and load current regulation based on generator model. The generator controller is designed by combining adaptive control with backstepping algorithm and then the simulation model is built in Simulink for simulation verification. The simulation results show that the controller designed in this paper has better dynamic performance, better damping stability margin and wider frequency range response than the existing controller. Finally, the experimental results based on Dual DSP hardware platform prove the rationality and effectiveness of the controller.
