The paper uses a discrete model of the permanent magnet synchronous machine. The proposed algorithm makes it possible to consider the errors in measurements of current, voltage, and electrical angular speed. Extended instrument variables are used to identify parameters. To solve the overdetermined system, total least squares are used. This makes it possible to improve the accuracy of estimates of extended instrumental variables on a finite sample. The simulation results confirmed the high accuracy of the resulting estimates. © 2022 IEEE. |

Recent studies have shown that for some high-performance servo applications, PMSM can be a serious competitor face the induction machine (IM). The PMSM mathematical model is created based on Park and Clarke transformations. This is to achieve linear dynamics similar to a DC motor. The vector control principle is applied on the PMSM. In order to achieve linear dynamics similar to that of a DC motor. There are two control loops in the linearized model, namely, the current and the speed loops. The aim of the control system is to achieve a quick response. Finally, a control system for the PMSM was created, and the entire motor was tested. The collaborative optimization control experiment, as well as torque tracking and speed restriction tests, validate the correctness and effectiveness of the suggested control technique. The performance of the PMSM drive system under different speeds is evaluated using the MATLAB/Simulink tool. © 2021 IEEE. |

Synchronous motor observability study and a new robust MRAS speed observer with an improved zero-speed position estimation design for surface PMSM Article de journal Dans: WSEAS Transactions on Systems and Control, vol. 5, no. 7, p. 567-580, 2010, ISSN: 19918763, (cited By 5). Résumé | Liens | BibTeX | Étiquettes: AC motors; Adaptive systems; Estimation; Magnetic devices; Observability; Speed; Synchronous motors; System stability, Permanent magnets @article{Zaltni2010567, This paper deals with the Permanent Magnet Synchronous Motor (PMSM) observability problems and proposes a simple and effective solution to improve the rotor speed and position estimation for Surface PMSM (SPMSM). In fact, the problem of loss of observability at low frequency range is always recognized in experimental settings. Nevertheless, there are no sufficient theoretical observability analyses for the PMSM. In the literature, only the sufficient observability condition has been presented. Therefore, the current work is aimed specially to the necessary observability condition analysis. In order to improve the rotor speed and position estimation in the case of SPMSM, a special attention is given to Model Reference Adaptive System (MRAS). MRAS based techniques are one of the best methods to estimate the rotor speed and position due to its performances and straight forward stability approach. In this paper, we propose a new robust MRAS scheme based on sliding mode techniques to estimate the rotor speed of a SPMSM. Furthermore, an Estimator/Observer swapping system is designed to overcome position observability problems at zero speed which is an unobservable state point. The stability of the proposed MRAS observer is also presented and discussed. Various tests are carried out in simulation using MATLAB/SIMULINK to illustrate the obtained theoretical results. |

Nonlinear speed control using adaptive sliding mode and lyapunov approaches for PMSM fed by a 3-levels NPC inverter Article de journal Dans: Journal of Electrical Systems, vol. 6, no. 3, p. 350-360, 2010, ISSN: 11125209, (cited By 2). Résumé | Liens | BibTeX | Étiquettes: Adaptive Control; Lyapunov theories; NPC inverters; PMSM; Sliding modes, Electric inverters; Lyapunov methods; Synchronous motors, Permanent magnets @article{Zaltni2010350, A robust non linear strategy for high performance Permanent Magnet Synchronous Motor (PMSM) drives fed by a 3 levels NPC inverter is proposed. The developed approach leads to the design of Lyapunov theory in order to linearize the behavior of the PMSM. High accuracy and robustness to disturbances and parameter variations is obtained by designing an adaptive variable structure control (AVSC) to achieve speed tracking objective. The stability of the closed loop is demonstrated using Lyapunov theory. Extensive simulation work leads to significant results illustrating the good performances of the overall designed scheme. © JES 2010. |
