Hybrid Electric Aircraft Model Based on ECMS Control

The hybrid-electric propulsion control system plays a fundamental role to ensure the correct function of all components and to operate a performing energy management. Several control strategies have been proposed in the literature, but the challenge is to keep these techniques methodologically simple and easy to implement. In this paper, an analytical derivation of the Equivalent Consumption Minimization Strategy (ECMS) for energy management of hybrid-electric aircraft is presented, based on Pontryagin’s Minimum Principle (PMP). Simulation results obtained for a parallel hybrid electric configuration with a maximum take-off power of 134 kW are also presented.
