Abstract

This paper presents a variable structure type sliding mode control (SMC) under current mode control for dc-dc boost type converter having non-minimum phase characteristic. The robustness of the proposed controller is verified for load and line variations. To reduce the chattering and to improve stability, a fuzzy sliding mode control (FSMC) is designed. A detailed derivation of control law is presented by using Flippov´s method and Lyapunov method for SMC and FSMC respectively. Simulations are carried out using MATLAB/SIMULINK software. The simulation results are presented.
