Trajectory Tracking Method Designing based on Adaptive Fast Convergence Terminal Sliding Mode Control

Abstract

Concerning the plan trajectory tracking problem of gliding missile, the fast convergence sliding mode control is used in the designing of guidance law. To cope with the problem of parameter perturbation, adaptive method is proposed to update the value of parameter timely. Theoretical analysis and numerical simulation show our method can estimate the angular rate of missile precisely, and performs well in trajectory tracking.
