Les entra\u00eenements \u00e9lectriques polyphas\u00e9s ont acquis une importance\u00a0particuli\u00e8re ces derniers temps pour leur utilisation dans des applications o\u00f9 la fiabilit\u00e9\u00a0pr\u00e9sente un int\u00e9r\u00eat pour des raisons \u00e9conomiques et de s\u00e9curit\u00e9. Cette th\u00e8se se centre sur\u00a0le d\u00e9veloppement de techniques de commande en mode instantan\u00e9 pour contr\u00f4ler de\u00a0mani\u00e8re optimale les machines polyphas\u00e9es, en analysant leur tol\u00e9rance dans diff\u00e9rentes\u00a0conditions de fonctionnement, telles que lors de l\u2019atteinte de limites \u00e9lectriques (limites\u00a0de tension, de courant et de niveau maximum de magn\u00e9tisation) ou de d\u00e9fauts de type\u00a0phase ouverte. Tout d\u2019abord, la technique DTC est propos\u00e9e pour g\u00e9rer le cas de d\u00e9faut\u00a0de type phase ouverte dans la machine polyphas\u00e9e. Une comparaison de la tol\u00e9rance \u00e0 la\u00a0d\u00e9faillance des commandes de type DTC par rapport \u00e0 d\u2019autres techniques de\u00a0commande est r\u00e9alis\u00e9e, permettant une conclusion sur les forces et les faiblesses des\u00a0m\u00e9thodes analys\u00e9es. Enfin, un contr\u00f4leur de courant optimal est d\u00e9velopp\u00e9 utilisant des\u00a0techniques MPC permettant une utilisation optimale de la capacit\u00e9 de couple du syst\u00e8me\u00a0en cas de limitations \u00e9lectriques. Des r\u00e9sultats de simulation et des validations\u00a0exp\u00e9rimentales sont effectu\u00e9s pour corroborer les approches initiales, en utilisant des\u00a0cas particuliers d\u2019entra\u00eenements pentaphas\u00e9s command\u00e9s avec diff\u00e9rents sous-espaces\u00a0de commande dans le domaine fr\u00e9quentiel.<\/p>\n

Novel control techniques in multiphase drives: Direct control methods (DTC and MPC) under limit situations<\/span><\/strong><\/span><\/b><\/p>\n

Abstract<\/span><\/strong><\/p>\n

Multiphase drives have gained special relevance in recent times for their\u00a0use in applications where reliability is of interest for economical and safety reasons.\u00a0This Thesis focuses on the development of direct control techniques to optimally\u00a0control multiphase machines, analyzing their tolerance to different limit operating\u00a0conditions, such as electrical constraints (voltage, current and magnetization level\u00a0limits) or failure situations such as an open-phase fault. First, the DTC technique is\u00a0proposed to manage the open-phase fault operation of the multiphase machine. A\u00a0comparison of the fault-tolerant capability of DTC with other control techniques is\u00a0carried out, to conclude the strengths and weaknesses of the analyzed methods facing\u00a0this limit operation. Finally, an optimal current controller is developed using MPC\u00a0techniques that allows the optimal utilization of the system\u2019s torque capability under\u00a0electrical limitations. Simulation results and experimental validations are obtained to\u00a0corroborate the initial approaches, through the use of particular cases of five-phase\u00a0drives controlled using different frequency-domain control subspaces.<\/p>\n
