While the notion of a hybrid fuel cell vehicles is conceptually promising, due to an off-loading of peak power demands from the fuel cell to the storage devices, the questions of device coordination is unsettled. Clearly the prominent role of equipment limitations, with respect to energy storage capacity and maximum power, suggests the use of predictive control for constraint enforcement. In this work an MPC tuning method specifically tailored to the hybrid vehicle application is presented. The approach is based on the notion of backed-off operating point selection and has the objective of minimizing energy losses from the storage devices. In addition, a soft constraint formulation unique to hybrid vehicle application is proposed.
