Full textThe work presented is focused on the design and development of a magnetic circuit for high efficiency motors of medium and small powers. It is built with non-segmented laminations of Grain Oriented (GO) steel. Experimentations on magnetic circuits excited under unidirectional magnetic field are performed. Such tests aim the comparison of the GO structure global characteristics with those of a classic one composed of Non-Oriented (NO) steel, allowing seeing the superiority of the GO structure in terms of iron losses. Local experimentations, followed by a numerical model, allow the analysis of the local distribution of the magnetic flux within the structure, leading to its optimisation. Such technique of assembly is then tested under rotational magnetic field. In that context, several experimentations are performed and its performance is compared with the one of a NO prototype. The final stage consists in testing the developed structure in induction motors built withthis GO assembly. Several characteristics are measured or estimated (IEC standard) and compared with those obtained on the initial NO motor. The GO structure efficiency leads to a remarkable reduction of the static losses, allowing the increase of the global efficiency of the motor

Full textThe control laws of AC machines, asynchronous and synchronous, are pretty mature today. Vector control is a general framework for AC machines' modeling, analysis, and control. A model-based synthesis approach is often used, and the control law parameters are defined according to the machine parameters. A standard variable speed drive is used in most industrial applications to control the speed of the motor powered by the electrical network. In this case, the drive is called a “general-purpose drive”. Depending on the type of AC machine, a specific controller is needed. This will require the drive's manufacturers to include different control laws in their drive. Consequently, adding these laws will require a lot of memory and computing capacity. Furthermore, changing the machine type would alter the control law. This problem could lead to many issues such as higher installation costs, commissioning time, and additional tuning. For this reason, the search for a "universal drive" scheme has been going on for more than one decade.This thesis presents an in-depth study on the subject of unified control for AC machines. Our goal is to innovate a unified control law for electric machines, particularly asynchronous and synchronous machines, for use in future general-purpose variable speed drive products. As a part of this thesis, we address the unification of modeling, observer design, and control aspects in the context of AC machines. For decades, the AC models have been studied separately in the literature. However, thanks to the similarities between electric machines, a unified modeling framework is proposed. The unified model relies on easily identifiable stator equivalent parameters regardless of the specific type of machine. Based on the unified model, a key contribution was made in this study, which is the design of three novel unified flux observers to track rotor or stator flux positions, regardless of the motor type. Thanks to the unified flux observer, a unified vector control law for AC machines becomes possible. Experimental data verify the proposed control law for induction machines and permanent magnet synchronous machines. Theoretically, the proposed solution highlights the potential for a “universal AC motor drive" that doesn't need any information on the motor type. However, the unified control law performs poorly at low speeds, where a unified startup method is needed

Full textThe interest in the electric vehicles rose recently due both to environmental questions and to energetic dependence of the contemporary society. Accordingly, it is necessary to study and implement in these vehicle fault diagnosis systems which enable them to be more reliable and safe enhancing its sustainability. In this work after a review on problem of faults in the drivetrain of series hybrid electric vehicles (SHEV), a deep investigation on fault diagnosis of AC-DC power converter and permanent magnet synchronous motor (PMSM) have been done as two important parts of traction chains in SHEVs. In other major part of this work, four types of faults (stator winding inter turn short circuit, demagnetization, eccentricity ant bearing faults) of a PMSM have been studied. Inter turn short circuit of stator winding of PMSM in different speeds and loads has been considered to identify fault feature in all operation aspects, as it is expected by electric vehicle application. Experimental results aiming short circuits, bearing and eccentricity fault detection has been presented. Analytical and finite element method (FEM) aiming demagnetization fault investigation has been developed. The AC-DC converter switches are generally exposed to the possibility of outbreak open phase faults because of troubles of the switching devices. This work proposes a robust and efficient identification method for data acquisition selection aiming fault analysis and detection. Two new patterns under AC-DC converter failure are identified and presented. To achieve this goal, four different level of switches fault are considered on the basis of both simulation and experimental results. For accuracy needs of the identified pattern for SHEV application, several parameters have been considered namely: capacitor size changes, load and speed variations. On the basis of the developed fault sensitive models above, an ANN based fault detection, diagnosis strategy and the related algorithm have been developed to show the way of using the identified patterns in the supervision and the diagnosis of the PMSM drivetrain of SHEVs. ANN method have been used to develop three diagnosis based models for : the vector controlled PMSM under inter turn short circuit, the AC/DC power converter under an open phase fault and also the PMSM under unbalanced voltage caused by open phase DC/AC inverter. These models allow supervising the main components of the PMSM drivetrains used to propel the SHEV. The ANN advantages of ability to include a lot of data mad possible to classify the faults in terms of their type and severity. This allows estimating the performance degree of that drivetrains during faulty conditions through the parameter state of health (SOH). The latter can be used in a global control strategy of PMSM control in degraded mode in which the control is auto-adjusted when a defect occurs on the system. The goal is to ensure a continuity of service of the SHEV in faulty conditions to improve its reliability

High speed motor is often adopted in the air conditioner and machine tool to achieve energy saving and high speed manufacture. The objective of this research is to develop the drive technology for induction motor (IM) with high speed. Vector control (VC) is essential for a precise speed and torque control of the IM. This research employs an indirect VC that estimates the rotor speed and slip to achieve a speed sensorless control. Precise rotor speed estimation relies on precise machine parameter estimation. This research presents an auto tunning method that uses DC test, lock-rotor test and no load test to estimate the equivalent circuit parameters of the IM. Accordingly, the sensorless speed estimation and indirect VC are designed. A sliding mode back EMF estimation method is adopted to reduce the speed error due to parameter variation caused by the inevitable temperature rise. To make a smooth full range speed control, a dynamic filter is developed to adjust the cut-off frequency of the low-pass filter to obtain a low ripple speed feedback. A fully digital controller is realized using the TI F28335 DSP IC. The firmware is programmed with the auxiliary design of the PSIM SimCoder digital control developing platform. A 2kW IM drive is implemented. The effectiveness of the proposed method is confirmed with some simulation and experimental results.
