Abstract

This paper proposes a second order sliding mode controller (SOSMC) for industrial process control applications. This SOSMC overcomes the problem of chattering occurred in classical sliding mode controller (SMC). The chattering is the major drawback of SMC. So that proposed controller is designed to achieve smooth and suitable control input for practical systems. The performance of the designed controller is verified in simulation and compared with existing well known super twisting SOSMC to prove the performance of the proposed controller for the process control systems such as a level control of coupled tank system and a concentration control of chemical continuous stirred tank reactor (CSTR) system. The simulation is performed on the mathematical models of both mentioned systems to show the applicability of the proposed method for process control systems.
