The variable structure control problem of discrete-time system is designed by using the discrete-approach law. Based on the attenuation control, the approach law of attenuation speed and the approaching law of attenuation power are proposed. Theoretical analysis and simulation results show that the proposed method The method is effective, which not only guarantees the gradual stability of the closed-loop system but also greatly reduces the jitter of the system.
