A Proposal of Dynamic Sliding Mode Controller for Integrating processes with Inverse Response and Deadtime

Abstract

This document aims to design a dynamic sliding mode controller for integrating systems with inverse response and deadtime based on a reduced model of the process, which is incorporated into a hybrid control scheme composed by a dead time compensator called Smith predictor, and to counteract the effects of the inverse condition, the compensator designed by Iinoya and Alpeter is used to provide robustness to the control topology. Besides, the rejection of load disturbances oversees a PD controller, which is added to the inner loop of the control structure. Being a complex dynamic system, the proposed controller is a promising alternative. Moreover, it allows a comparative analysis against traditional controllers such as PIDs, whose performance decreases drastically under these unfavorable conditions.
