Multiphase motors are increasingly used in high-performance industrial applications due to their improved efficiency, reliability and fault tolerance compared to traditional three-phase machines. However, one of the persistent challenges in their control is the presence of speed ripples, which can degrade performance, increase mechanical stress and reduce system life time. This paper proposes a control strategy based on adaptive gain fuzzy logic applied to the vector control of a five-phase motor. Unlike conventional fixed-gain controllers, this approach allows the controller gains to be dynamically adjusted according to the state of the system, thus increasing robustness to disturbances and load variations. Fuzzy logic enables the controller's behaviour to be modelled according to linguistic rules inspired by human expertise, making the system more responsive and intelligent. Simulation results obtained using Matlab show a significant improvement in speed stability and a marked reduction in ripples, confirming the effectiveness of the proposed method.. Keywords – PI- controller; five-phase asynchronous machine; fuzzy logic, speed oscillations.

Abstract – The resonant frequency and bandwidth of a printed antenna can be modified by varying the physical parameters of the structure. The circular printed antenna with an air-gap proposed here enables these characteristics to be modified without having to design and build a new printed antenna. Its resonant frequency can be modified by adjusting the height of the air gap between the substrate of the radiating element and the ground plane. In addition, the presence of an air gap significantly increases the bandwidth of the a printed antenna. Our first step was to characterize the resonance and bandwidth of this type of antenna theoretically, using the integral equation technique, the moments method via the Galerkin procedure applicable for numerical resolution. To achieve this, the mode systems (TM, TE) derived from the cavity model were used as Chebyshev basis functions to present the current distribution on the conductive disk. Our results are in good agreement with the theoretical results previously published in the literature. In order to validate this study, practical realizations of this type of structure were carried out at the IUT de Chartres -Institut PRISME- to compare our results with real measurements. Good agreement was again found, confirming the interest of this type of antenna. Keywords – air-gap ; physical parameters ; Chebyshev Basis Functions ; Galerkin procedure; theoretical results

Operation at low speed and high torque can lead to the generation of strong ripples in the speed, which can deteriorate the system. To reduce the speed oscillations when operating a five-phase asynchronous motor at low speed, in this article, we propose a control method based on Gray Wolf optimization (GWO) algorithms to adjust the parameters of proportional–integral (PI) controllers. Proportional–integral controllers are commonly used in control systems to regulate the speed and current of a motor. The controller parameters, such as the integral gain and proportional gain, can be adjusted to improve the control performance. Specifically, reducing the integral gain can help reduce the oscillations at low speeds. The proportional–integral controller is insensitive to parametric variations; however, when we employ a GWO optimization strategy based on PI controller parameters, and when we choose gains wisely, the system becomes more reliable. The obtained results show that the hybrid control of the five-phase induction motor (IM) offers high performance in the permanent and transient states. In addition, with this proposed strategy controller, disturbances do not affect motor performance.

Today, as a result of significant progress in the area of control of electrical machines, new techniques and approaches have emerged. In order nonlinear or having non constant parameters systems, conventional control laws may be inadequate because some performance can not be guaranteed in the presence of structural variations or external disturbances. It is then necessary to synthesize robust controls with respect to these disturbances. It is in this context that we propose in this work a new command combines the study of adaptivity with the uncertainty that derives adaptive fuzzy controllers. This study presents the directadaptive fuzzy control stability extended, which uses the theory of approximation and the theory of Lyapunov to establish a parametric adaptation law ensuring the stability and boundedness of all the control signals and the tracking error. The obtained results show that direct adaptive fuzzy control stability extended has proved a great effectiveness and a strong robustness in the presence of parameter variations and disturbances.

The asynchronous machine currently holds a very important and ever-growing market thanks to its simplicity, robustness and low manufacturing cost. Despite these advantages, his command remains a more complex in comparison to the direct current machine, the use of fuzzy control is an interest having regard to its ability to treat the imprecision and uncertainty. If the variable dynamic systems impose the adjustment of the parameters of the controller and if the base of rules of order is difficult to build, the introduced of the adaptive techniques of control is necessary. Consequently, the combination of the study of adaptivity and uncertainty made it possible to derive the adaptive fuzzy controllers. In this context, several schemas of adaptive fuzzy controller have been proposed, among them the indirect adaptive fuzzy control In the indirect approach, the fuzzy systems are used to estimate the system dynamics and control law is obtained from the estimated. With through the obtained results, indirect adaptive fuzzy control based on the inverse identification has proved a great effectiveness and a strong robustness in the presence of parameter variations and disturbances.

this paper presents an advanced direct adaptive fuzzy control for asynchronous machine which uses the theory of approximation and the theory of Lyapunov to establish a parametric adaptation law ensuring the stability and boundedness of all the control signals and the tracking error. In the direct approach, the fuzzy system is used to describe directly the control law and the parameters of the fuzzy system are directly adjusted to achieve the control objectives. Through the obtained results, stable direct adaptive fuzzy control generalized has proved a great effectiveness and a strong robustness in the presence of parameter variations and disturbances.

La machine asynchrone, dont la structure simple fait le succès industriel, devient redoutablement complexe lorsqu’il s’agit d’en étudier une commande performante. Le recours à la commande par la logique floue trouve un intérêt important auprès des chercheurs, vu sa capacité de traiter l’imprécis, l’incertain et le vague. Si les systèmes dynamiques variables imposent l’ajustement des paramètres du régulateur et si la base de règles de commande est difficile à construire, les chercheurs ont introduit les techniques de commande adaptatives. Par conséquent, la combinaison de l’étude de l’adaptativité et de l’incertitude a permis de dériver les contrôleurs flous adaptatifs. Dans ce contexte, plusieurs schémas de commande floue adaptative ont été proposés, parmi eux la commande floue adaptative directe linéarisante ou l’étude de la stabilité est fondée sur l’approche de Lyapunov.
