Trajectory Tracking Control Method Based on Adaptive Higher Order Sliding Mode

To resolve the problem of high-precision trajectory tracking control under interference conditions in a missile’s mid-guidance phase, according to constructed nominal trajectory, an improved adaptive high-order sliding mode controller (AHSTC) is proposed. In this method, open-loop trajectories are established nonlinear programming and Gaussian pseudospectra method. A developed by designing surface approaching law combined with error model. verify effectiveness superiority proposed analysis simulation carried out through example missile phase control. Compared linear quadratic regulator (LQR) active disturbance rejection (ADRC) results show that AHSTC method shows faster convergence effect. Therefore, has good engineering application value.
