摘要: This thesis is a contribution to the control of Hybrid Excitation Synchronous Machine (HESM) in embedded applications. The HESM combines advantages Permanent Magnets (PM) machine and wound rotor machine. excitation flux this produced by two different sources: PMs DC field winding that placed at stator preserve brushless structure. latter source used air gap. model based on Park takes into account iron losses magnetic circuit saturation effect. electric parameters laboratory prototype are identified. controlled generator mode motor mode. In power generation system, study treats particular aircraft supply more aircrafts. Two distribution networks studied: High voltage variable frequency network high network. case, coupled diode bridge rectifier. both cases, aims maintain output magnitude equal its reference via action current only. scalar. Simulation with Matlab/Simulink experiments validate approach. For mode, attention paid propulsion an vehicle. An optimal minimal elaborated. copper considered first place. Iron added next. Finally, optimization problem extended it includes due inverter chopper. Analytical expressions armature currents computed using Lagrange multiplier method (Kuhn-Tucker conditions). software proves analytical solution yields indeed combination guarantees over New European Driving Cycle.
