Abstract—This paper deals with the modelling, analysis design and experimental validation of a robust control method for a permanent magnet synchronous machine (PMSM) supplied with a PWM inverter based on a monovariable H infinity standard controller. Under the influence of uncertainties and external disturbances, by a variation of ±10% of all motor parameters from the nominal values, the robus...

In this paper a small scale wind generator based on a permanent magnet synchronous machine (PMSM) and associated with an indirect maximum power point tracking (MPPT) algorithm is proposed. Choosing an energy conversion active structure and a sensorless PMSM, to control the system, a speed estimator is required. Facing to other methods, the extended Kalman filter (EKF) model-based estimator allo...

The speed sensorless control of nonsalient PMSM that uses estimated rotor flux instead of the transformation angle is designed. This paper introduces a new sequential switching control strategy for a current control of a three phase inverter. The key idea is to integrate the benefits of the variable structure system control design and the event-driven sequential control structures to raise the ...

In the paper by Vaclavek et al. (IEEE Trans. Ind. Electron., vol. 60, no. 8, pp. 3047-3059, Aug. 2013), the local observability of both induction machine and permanent magnet synchronous machine under motion sensorless operation is studied. In this letter, the “slowly varying” speed assumption is discussed, and the permanent magnet synchronous machine observability condition at standstill is re...

This work deals with parameter identification of permanent magnet motors, a class of ac motor which is particularly important in industrial automation due to characteristics like applications high performance, are very attractive for applications with limited space and reducing the need to eliminate because they have reduced size and volume and can operate in a wide speed range, without indepen...

This paper describes the optimum design of a permanent-magnet-assisted reluctance rotor of a 110 kW reluctance synchronous traction machine. Previous studies show that the performance of the pure reluctance synchronous machine drive deteriorates fast in the flux-weakening speed region. To address this problem, thin bonded permanent-magnet sheet material is used inside the flux barriers of the r...

This The Permanent Magnet Synchronous Motors (PMSM) are used for medium power applications and preferred over conventional motors like Induction and Synchronous motors due its superior performance, efficiency and controllability. Normal voltage source inverters are suitable only for three phase drives. Cascaded multi-level inverters are used to improve the power quality. The Hexagram inverter h...

Permanent Magnet Synchronous Motor (PMSM) drive is being preferred in industrial automation due to high efficiency, compact structure, and high torque to weight ratio and so on. PMSM have been widely used in variable speed drives. The direct torque control (DTC) technique for a PMSM motor is receiving increasing attention due to the important advantages as the elimination of the current control...
