Abstract:

Aiming at the composite disturbance problem caused by unmodeled friction disturbance, parameter uncertainty, and external random disturbance in the rolling channel control for a trajectory correction fuse with active-canards, a sliding mode control method based on the extended state observer (ESO) is proposed. Firstly, the model of the rolling channel of the trajectory correction fuse is established. The external disturbances, unmodeled friction force and parameter perturbations are integrated into a composite disturbance. Then the ESO is designed to estimate the state variables and composite disturbances that are difficult to directly measure in roll channel model of correction fuse, and the roll channel controller is designed based on the estimated values and the sliding mode control theory to realize the accurate tracking of the roll angle command. Comprehensively considering the closed loop control system composed of ESO and sliding mode controller, Lyapunov stability theory is used to prove the stability of the proposed loop control system. Finally, the simulation result verifies that the roll channel has great performance of instant response to roll angle indicator, which can effectively surpass the composite disturbance, and has strong robustness and good stability.

Key words: trajectory correction fuse with active-canards, roll control, extended state observer (ESO), sliding mode control, disturbance estimation and compensation techniques
