A Linear Quadratic Integrator Approach for a Hydrogen Genset Control

Abstract

This paper presents a Linear Quadratic with Integrator (LQI) controller for a hydrogen genset (internal-combustion combustion engine generator) which is used to extend electric vehicle range. Since the genset efficiency depends mostly on generator rotor speed and produced power, a maximum efficiency tracking method is required. The optimal operating conditions provided by the efficiency tracking module must be imposed to the genset. Thus, we proposed a LQI controller for dynamically driving genset operating conditions toward the optimal one. This controller is based on a state space model in which the genset parameters are identified offline using the Least-Square (RLS) algorithm. Preliminary evaluation using real genset data with this type of controller demonstrated the effectiveness of the proposed approach.
