Abstract:

Suitable controller design for Boost converter is important to increase its performance in various applications like renewable energy integration and control circuitries. Linear controller are proved to be inefficient under varying operating conditions. Sliding Mode Controller (SMC) is a nonlinear controller offering advantages of robustness, fast dynamic response and ease of implementation. In this research work, SMC for Boost converter is proposed and analyzed using MATLAB® SIMULINK® as simulation platform. State space modelling technique is used for Boost converter. Proposed SMC comprises of two loops; voltage and current, controlled by Proportional Integral (PI) and Hysteresis respectively. Simulation of Boost converter with proposed controller shows good response in terms of less overshoot and settling time for initial transient, supply, load and reference variations.
