Non-linear state space model and control strategy for pem fuel cell systems.

This paper presents a non linear state space model and a linear control system for a Polymer Electrolyte Membrane fuel cell. The dynamics modeled are the temperature of the stack and the air fl ow compressor, and their main feature is the reproduction of the oxygen excess ratio behavior. The linear...

Description
Summary:This paper presents a non linear state space model and a linear control system for a Polymer Electrolyte Membrane fuel cell. The dynamics modeled are the temperature of the stack and the air fl ow compressor, and their main feature is the reproduction of the oxygen excess ratio behavior. The linear control system is a linear quadratic state feedback regulator and a Kalman fi lter, where the control objective is to avoid oxygen starvation and to minimize fuel consumption, through the tracking of an optimal load power profi le. The Kalman fi lter is designed in order to obtain information from some non-measurable states.
