New Time-Varying Sliding Surface for Switching Type Quasi-Sliding Mode Control

This study considers the problem of energetical efficiency in switching type sliding mode control discrete-time systems. The aim this work is to reduce quasi-sliding band-width and, as follows, necessary input, through an application a new time-varying hyperplane sampled time Although hyperplanes are well known provide insensitivity matched external disturbances and uncertainties model whole range motion for continuous-time systems, their case has never been studied detail. Therefore, paper proposes surface, which crosses system’s representative point at initial step then shifts state space according pre-generated demand profile variable. Next, controller real perturbed plant designed so that it drives its reference position on plane each step. impact trajectory minimized, leads reduction effort. Moreover, thanks reaching law applied generator, surface shift strictly limited occurs. Finally, under assumption boundedness smoothness disturbance, compensation scheme added. It proved strategy reduces from O(T) O(T3) order very beginning regulation process. shown maximum variable errors become well. These achievements directly energy consumption closed-loop system, nowadays one crucial factors engineering.
