Nguyen, Duy-Minh. "Commande intermittente de la machine à réluctance variable à double saillance". Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLS197/document.
Testo completoThe intermittent control aims to increase the efficiency of the machine-converter system by reducing the losses. In the purpose to maintain the average torque of the machine required by the load, this control increases the reference torque and turns off some phases during each electrical period or each mechanical period. By this fact, it reduces the converter losses and the ferromagnetic losses of the machine. It also has a freedom in the selection of the activated phases which influences the generated frequencies of the current, the radial force and the torque. Therefore, this strategy of the intermittent control, which is called sliding strategy, can avoid the excitation of the natural frequencies of the stator, or those of the drivetrain. It aims to reduce the negative effects of the intermittent control vis-à-vis the vibration of the stator and the pulsation of the drivetrain which are respectively at the origins of acoustic noise and mechanical jerks. Finally, the intermittent control is validated on driving cycles and can save up to 5.17 % of the consumed electrical energy

Testo completoFor electric vehicles, traction from storage battery to the wheels through the engine is the heart of the system. It regularly enjoys technological innovations making this vehicle more attractive. Currently, machines offered by manufacturers are classic, synchronous and induction machines. With complex laws, they offer good performance.However, manufacturers are exploring new unconventional machines to reduce their manufacturing cost while maintaining performance. One possible solution is the switched reluctance machine (SRM). Indeed, its design is simple and made of inexpensive materials. Its rotor completely passive gives it a very good robustness and high rotational speed required for certain compactness. However, its operation is much more complex than for other machines, it is relatively noisy and has significant torque ripple.Our work contributes to the improvement of SRM’s performance in terms of control torque characteristics and global efficiency over a large range speed. They were driven on two axes: one control axis and one design axis.To satisfy a torque control as perfect as possible, new currents controller both efficient and relatively simple to implement on software target were first presented. Then we proposed a SRM's control implementation on hardware and software targets. The objective is to maintain the performances in the case of an important sampling period, especially at high speeds. So an FPGA circuit (Fied Programmable Gate Array) was used.To improve torque characteristics depending on the speed, and global efficiency, a new SRM structure has been proposed. It is provided with an auxiliary coil creating a magnetic excitation in each phase. A study was initially conducted using simulations based on a new model. It helped to highlight the benefits of excitement compared to a conventional SRM. To validate the results, a prototype was then designed, built and tested.An important part of this work has been devoted to the implementation of experimental platforms and implementation of numerous tests to validate the theoretical developments, both in terms of control on a 8/6 SRM and design on a 6/4 SRM

Testo completoAn analytical model of doubly salient switched reluctance machine magnetic noise prediction and a new technique of active noise reduction are proposed. The studied machine is described as well as the analytical expressions permitting the determination of mechanical deformations and acoustic intensity. The main contribution of this research consists in determining analytical expressions of magnetic origin forces which create vibrations and noise. A 2kW 8/6 machine permits to validate several theoretical points such as mechanical resonance frequencies, phase inductances or vibratory and acoustical spectra. Existent noise reduction process are also described as well as influences of geometric parameters - such as teeth or yoke dimensions- on noise. At last, a new technique using current injection into auxiliary windings is performed and validated on an available prototype

Testo completoThe present work concerns, at first, the sizing of switched reluctance machine with its associated inverter. We identified the most important parameters which can play an important part on the weakening of the machine: stator and rotor angles, air gap, and number of turns… After that, we proposed a methodology for the elaboration of control laws that can be easily implemented into a numerical embedded control. These laws, based on preliminary parametric studies, was developed in order to limit torque ripple at low speed and to ensure high global efficiency at high speed. In the final part of the thesis, we proposed a new control mode called continuous mode. By using this mode, the torque and then power in field weakening mode can be increased considerably without any hardware modification. Moreover, this continuous the impact of design trade-offs
