Optimal speed trajectory tracking of an AC motor drive system with simultaneous minimization of its electromagnetic losses and fuzzy logic efficiency optimization in steady and transient statesOptimal speed trajectory tracking of an AC motor drive system with simultaneous minimization of its electromagnetic losses and fuzzy logic efficiency optimization in steady and transient states Δημοσίευση σε Συνέδριο Conference Publication 2015-11-142006enThe present work improves the efficiency for an Induction Motor (IM) drive by: (a) Off-line calculation of an optimal speed profile in order to achieve minimum total electromagnetic losses (machine and converter system losses) as well as to maintain satisfactory dynamic performance, over an closed-cycle operation. This speed profile is adjusting input to the drive either by off-line programming or on-line closed loop control. (b) On-line fuzzy logic adjustment of the magnetizing current in order to achieve the minimum input dc power during transient and steady states. Simulations results confirm the validity of the proposed method and experimental results will be available upon conclusion of the laboratory testings.http://creativecommons.org/licenses/by/4.0/Proceedings of the 2006 International Conference on Electrical Machines Sergaki Eleftheria Σεργακη Ελευθερια Stavrakakis Georgios Σταυρακακης Γεωργιος Electric engineering electrical engineering electric engineering
