Advanced Strategies for Chattering Reduction in Sliding Mode-Controlled Bidirectional Cuk Converters

Abstract

Sliding Mode Control (SMC) is a robust control technique widely used for managing nonlinear systems with uncertainties and disturbances. It has many advantages like Robustness to System Uncertainties, Simple Implementation, Finite-Time Convergence, Insensitivity to Nonlinearities, Stability and Robust Performance. Despite its advantages significant challenge in SMC is the phenomenon of chattering, characterized by high-frequency oscillations of the control signal around the desired sliding surface. This paper provides a comprehensive investigation into the chattering issues associated with HOSMC and ASMC in power converters, examining the causes, consequences, potential mitigation techniques. Comparative analysis explains that, both HOSMC and ASMC improve the dynamic response and stability of bidirectional converters, ensuring efficient and reliable operation.
