Research on hxtension Control of Brushless DC Motor of the Quad-rotor

Due to the existence of nonlinear, multi-variable coupled of internal mismatch and wind of external disturbances, the Extension control is designed to fulfill the auto-tuning of control parameters for pitch, roll and yaw angle. Building Matlab simulation model to verify the control effect of the Extension controller, and programming GUI monitoring interface on three-dimensional trace and attitude angle of quad rotor on computer. Simulink simulation results show that: The Extension controller can effectively suppress the overshoot of the system and improve the response speed.
