Auto-disturbances-rejection controller design and its parameter optimization for aircraft longitudinal attitude

The auto-disturbances-rejection controller (ADRC) is proposed to design controller for aircraft longitudinal attitude. According to the influence to the system performance when parameter changing, the parameters were self-adjusted by GA. This method doesn’t depend on the experience of human heavily. Without changing the structure and parameters of the controller, the simulation results indicate that it achieves robustness performance and anti-disturbance performance for the controller, high dynamic performance and steady state performance for the system in two different flight states.
