development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Extended SMC for a stand-alone wound rotor synchronous generator

In this paper, a sliding mode controller for the stator voltage amplitude of a stand-alone wound rotor synchronous generator is presented. The standard dq-model of the electrical machine connected to an isolated inductive load is obtained. Then, the control law is designed using sliding mode techniques. The controller introduces a dynamic extension so that the stator voltage amplitude has relat...

Eccentricity Fault Diagnosis Studying for a Round Rotor Synchronous Machine

The paper presents a mathematical base modeling combined to Modified-Winding -Function-Approach (MWFA) for eccentricity fault detection of a round-rotor synchronous machine. For this aim, a 6-pole machine is considered, and the machine inductances are computed by MWFA in healthy and also under eccentricity fault. A numerical discrete-time method has been proposed to machine modeling in voltage-...

Passivity-based control of a wound-rotor synchronous motor

This paper presents a new nonlinear passivity-based controller for a wound rotor synchronous machine, acting as a motor drive. The control objectives are stated in the dqframe, and the port-controlled Hamiltonian model is also obtained. A power flow analysis allows to state the control goals in terms of reactive power compensation and ohmic losses reduction. From the Hamiltonian structure, the ...
