Design and Analysis of Active Disturbance Rejection Attitude Controller for Loitering Munition

The wings of loitering munition could be unfolded in flight. In order to reduce the effects of the model parameter variations caused by the structural change and external disturbances, active disturbance rejection attitude controller is put forward. After analyzing the operating mode of loitering munition, the vehicle's lateral motion equations is built. And then the characteristics of ADRC is analyzed. Meanwhile, the design method and the principle of parameter setting are proposed. Particularly, six degrees of freedom nonlinear simulation model is operated with Simulink. A series of experiments are conducted, and comparative analysis between designed controller and PID controller is made. Simulation results show that the active disturbance rejection attitude control algorithm can not only accurately estimate and compensate the internal/external disturbances but also improve the robustness of the system with model uncertainty and the performance of the flight control system. So it has high practical value. Moreover the method of controller design and parameter tuning is a good reference.
