Very High Speed Flatness Based Current Control For A Permanent Magnet Synchronous Motor Application On Internal Combustion Engines Electrification

This paper proposes a current control strategy for very high speed permanent magnet synchronous machines fed by dc voltage source inverter. The control strategy is based on flatness properties. It allows mastering the trajectories of the state variables and inputs. This study is dedicated for electrification applications in automotive field where robust control is needed to maintain the stability of the high speed system. Simulations and experiments are presented to show the effectiveness of the proposed method in controlling the synchronous machine up to 150 krpm, its speed limit.
