Temperature regulation in a Continuous Stirred Tank Reactor using event triggered sliding mode control

Abstract

Continuous Stirred Tank Reactor (CSTR) is a typical example of an industrial equipment for chemical processes that exhibit dynamics of a second order nonlinear system. Nonlinear and coupled nature of CSTR pose challenges in design of robust control with larger operating region. Industrial processes require good state estimation and disturbance rejection. Under parameter variations and fast changing dynamics, an event based sliding mode controller is presented in this work to provide robustness to the system with an added benefit of saving energy expenditure. Robustness and efficacy of the controller have been confirmed using numerical simulations.
