Chattering free sliding mode controller for mismatched uncertain system

Abstract: In this paper a second order sliding mode controller is proposed for controlling systems with mismatched uncertainty. Stability of the system is guaranteed and the chattering in the control input is considerably reduced. Simulation results demonstrate the superiority of the proposed controller over the existing first order sliding mode controller designed to handle mismatched uncertainty.

“…In conventional SMC, chattering and high value of control signal can be one of the main operational problems during practical implementation of the controller. High‐frequency oscillations (chattering) lead to low control accuracy, high wear and tear of moving mechanical parts, and high heat loss in power circuits [2427].…”

“…However, the control law u (k) must be designed such that some reaching law must be fulfilled considering these uncertainties, mostly when the matching conditions are not achieved (Furuta, 1990;Gao et al, 1995;Kim et al, 2000;Sira-Ramírez, 1991;Yu et al, 2000;Yadav and Singh, 2012;Mondal et al, 2012;Qu et al, 2014). This part of the design of DVSC controllers is not directly carried out during switching the surface design phase.…”
