Controlling asynchronous machines is complex because of the non-linearity of the model and the coupling between stator and rotor quantities. Thanks to advances in power electronics, decoupled control techniques have been developed to reproduce the performance of DC machines, while eliminating mechanical constraints. However, in the case of polyphase machines, these control strategies remain limited due of the harmonics generated by the inverter, which degrade power quality. To address this issue, a new fuzzy logic control strategy is proposed, aimed at reducing parasitic currents and improving dynamic performance in a five-phase asynchronous machine. A comparison between vector control using conventional PI and fuzzy PI is considered, based on the dynamic responses of speed, torque and harmonic distortion rate, especially under load variations and during rotational reversals. The simulation results obtained in MATLAB demonstrate a significant enhancement in speed stability and a reduction in ripples, confirming the effectiveness of the proposed approach

Conceptual models are built with concepts and relationships between them to reach a unified view of domain problems. There are many kinds of conceptual models developed in different modeling languages, such as class diagrams and entity-relationship models. In this paper, the authors have developed a specific meta-model following the Ecore standard to define conceptual models. These domain-specific conceptual models can be automatically formalized as domain ontologies using model transformation with the technique of triple graph grammars into ontology formal descriptions in accordance with the defined Ecore meta-model of the language OWL (web ontology language). For ontology deployment, its OWL code may be generated from OWL models using model-to-code transformation guided by Xpand templates. A performance evaluation is realized using a benchmark from the university domain with very large conceptual models. Through the experiments, they validate the performance and we prove the exactness and the scalability of the automatic transformation process of conceptual models
