Design and Simulation of Double-loop Sliding Mode Controller for Missile Attitude

Abstract

Sliding mode control has the advantages of simple controller design, short control time, strong anti-interference ability and easy physical implementation, so it is widely used in missile control. Combining the attitude dynamics and attitude kinematics of the missile, this paper designs two missile attitude control methods by using sliding mode control. The two controllers using the two-loop sliding mode control scheme can well track the expected inputs of the angular velocity and angle. And the controllers can work normally under small disturbance torque. So they have good traceability performance and robustness. In this paper, the missile attitude simulation is used to verify the accuracy, track performance and robustness of the two controllers, and compares the control effects of the two control methods.
