Abstract

In this paper, a state feedback controller is designed for a four-phase interleaved dcdc boost converter connected to PEM fuel cell to regulate the output voltage and current around desired values. The proposed controller features two loops based on state feedback, transforming the system into a state representation. The synthesis of the controller gains is validated using the Linear Quadratic Regulator (LQR) technique. To demonstrate its effectiveness, a typical proportional-integral (PI) controller based on the same average modelling is designed for further comparison and discussion. The performance metrics, including output voltage, source current ripples, settling time, and overshoot showcase the high robustness and dynamic characteristics of the proposed controller. The simulations are conducted using Matlab Simulink with a 1kW fuel cell system.
