Abstract
Purpose
The purpose of this paper is to propose two energy management strategies (EMS) for hybrid electric vehicle, the power system is an hybrid architecture (fuel cell (FC)/battery) with two-converters parallel configuration.
Design/methodology/approach
First, the authors present the EMS uses a power frequency splitting to allow a natural frequency decomposition of the power loads and second the EMS uses the optimal control theory, based on the Pontryagin’s minimum principle.
Findings
Thanks to the optimal approach, the control objectives will be easily achieved: hydrogen consumption is minimized and FC health is protected.
Originality/value
The simulation results show the effectiveness of the control strategy using optimal control theory in term of improvement of the fuel consumption based on a comparison analysis between the two strategies.

Abstract
Purpose
This work focuses on modelling, robust controller design and real time control of 3-DOF Helicopter.
Design/methodology/approach
This study presents an improved H∞ controller for this aerial vehicle
Findings
Simulation and experiment results are addressed to demonstrate the capability of this proposed control strategy to counteract the effect of this disturbance
Originality/value
In order to reduce the complexity of the standard H∞ structure, a fixed order control design is proposed as original approach
