Practical Sliding Mode Using State Depended Intermittent Control

Abstract

This brief introduces a practical sliding mode using state depended intermittent control strategy. Robust stabilization of the linear time-invariant system is achieved by rejecting the effect of matched and bounded input disturbances using the proposed state dependent intermittent sliding mode control (SDI-SMC). The system trajectories are driven to a predesigned practical sliding mode band by the proposed control to establish a practical sliding mode. The salient feature of the proposed control strategy is that the control is turned off whenever it is not necessary, which will result in a considerable saving in the control effort and other resources. The proposed SDI-SMC is simulated on the model of an industrial plant emulator and a detailed comparison is done with sliding mode control (SMC), event-triggered sliding mode control (ET-SMC) and adaptive sliding mode control (Adp-SMC).
