Control Method Research of Three-DOF Helicopter Based on Active Disturbances Rejection Controller

The flight control system of helicopter is difficult to control for their performance of high-order, multi-inputs multi-outputs and strong non-linear. This paper proposed a stability control algorithm of three-DOF laboratory helicopter based on active disturbances rejection controller (ADRC). Controlling the motion of axis guaranteed the tracking control in degrees of helicopter respectively. The stability analysis is carried through Lyapunov method. The results show that the algorithm compensate the disturbance and improve the system performance effectively.
