The permanent magnet synchronous machine with an external rotor is the most important device for high performance electrical drive systems in particular for hybrid electric vehicles. With such an application, the machine will operate in a wide speed range and on the other hand with very fast changing loads in both motor and generator operational modes. The paper discusses finite element analyse...

In this paper, a model of a variable speed wind turbine using a permanent magnet synchronous generator (PMSG) is presented and the control schemes are proposed. The model presents the aerodynamic part of the wind turbine, the mechanic and the electric parts. Simulations have been conducted with Matlab/Simulink to validate the model and the proposed control schemes.

A permanent magnet synchronous generator (PMSG) variable speed wind turbine connected to an electrolyzer and a battery model system is presented in this paper. Hydrogen gas could be produced from the model system, when a variable wind speed is applied to the PMSG driven variable wind turbine. The simulation results presented shows the nature of some of the variables of the PMSG wind driven turb...

This paper deals with the optimal control of interior permanent magnet synchronous machine (IPM) in the integrated starter-generator (ISG) application. IPM designed for flux-weakening operations are able to realise high performances. Nevertheless, the ISG environment imposes lots of constraints which must be taken into account in an appropriate control. After a presentation of machine design, I...

Flux switching permanent magnet synchronous motor (FMSM) has the characteristics such as large output torque, fast speed response and high reliability, so it can be widely used in the field of high-performance and high precision control.In the permanent magnet synchronous motor control system, the speed loop usually adopts the PI control algorithm. Although the PI control algorithm is relativel...

This paper presents the technical aspects, theoretical analysis, and comparisons of two new permanent magnet synchronous generator (PMSG) grid-interfaced models named PMSG boost and PMSG rectifierinverter. The exact feedback linearization (EFL) control scheme is used for the effective design and stability analysis of the aforementioned models. The complexity of the EFL control laws is discussed...

The mathematical modeling of open-switch faults in two-level machine-side converters and the fault-tolerant current control of isotropic permanent-magnet synchronous generators are discussed. The proposed converter model is generic for any open-switch fault and independent of the operation mode of the electrical machine. The proposed fault-tolerant current control system gives improved control ...

Various electric machines can be the candidate for electric vehicles applications, including induction machines, permanent magnet synchronous machines, switched reluctance machines, etc. Another class of machine, which has been relatively ignored, is synchronous reluctance machines. In order to enhance and increase torque density of pure synchronous reluctance machines, the low cost permanent m...

This paper presents an analysis by which the dynamic performances of a permanent magnet synchronous motor (PMSM) motor is controlled through a hysteresis current loop and an outer speed loop with different controllers. The dynamics of the wind turbine pumping drive system with (PI) and a fuzzy sliding mode (FSM) speed controllers are presented. In order to optimize the overall system efficiency...
