Abstract :
This paper presents an LPV/H∞ control strategy applied to power source coordination on board of average-power electric vehicles. The proposed approach concerns frequency separation of responses between three power sources in order to satisfy power demand of vehicle´s electrical motor, taking into account that sources are expected to work within distinct frequency ranges. The three sources - fuel cell, battery and ultracapacitor - are connected in parallel to a common DC-bus which supplies the electrical motor.
