In this paper an effort is made to represent the behaviour of a ship propulsion system comprising a Permanent Magnet Synchronous Motor (PMSM) driven by a 6-pulse driving system using the Direct Torque Control (DTC) control technique. The DTC technique cited is emulated via MATLAB's Simulink toolbox while all study cases are performed successfully in MATLAB's Power System Blockset environment.

The model of three-phase permanent magnet synchronous motor (PMSM) with loss of one phase or loss of one transistor is built and its fault tolerant direct torque control (DTC) is investigated. Extra-leg extraswitch inverter is put to use in the post-fault operation. Two different flux estimators are employed in order to calculate stator flux linkage & their corresponding torque and switching ta...

A permanent magnet synchronous motor (PMSM) plays an important role in the operation performance of electric vehicle. In order to increase speed stability PMSMs, improved sliding mode control (SMC) method is proposed this paper. Firstly, process a PMSM divided into parts, which are torque closed-loop and control. Secondly, integrated with proportional integral (PI) inverter switching frequency ...

This study obtains the analytical inverse system of a permanent magnet synchronous motor (PMSM) model based on traditional magnetic field orientation decoupling control mode by analyzing quality PMSM.

This paper presentsan investigation of a 3D-magnetic flux permanent magnet synchronous motor (3D-MF PMSM) used for electric vehicle applications. The investigated 3D-MF PMSM consists an integrated radial-flux and axial-flux structure. It has two air-gaps air-gaps, as well toroidal winding wound stator. structure helps to concentrate all the within maximize torque production. Moreover, there are...

An adaptive fuzzy control method is developed to control chaos in the permanent magnet synchronous motor drive system via backstepping. Fuzzy logic systems are used to approximate unknown nonlinearities, and an adaptive backstepping technique is employed to construct controllers. The proposed controller can suppress the chaos of PMSM and track the reference signal successfully. The simulation r...
