A Study on the Effect of Multivariable Control for Performance Improvement of a Fuel Cell Hybrid Test Train

Abstract

The fuel cell hybrid test train requires methods to control fuel cell output power. The acceleration and regenerative-brake performance of the train varies with the SOC of the battery. And the energy consumption also varies with the passenger occupancy and the ambient temperature. Therefore, we studied the traction performance and fuel consumption depending on the difference of the control methods and the number of parameters to be considered with using a driving energy simulator.
