Decoupling method of the Permanent Magnet Synchronous Generator using Singular Perturbation Theory

This paper proposes a decoupling method based on the singular perturbation technique applied to the permanent magnet synchronous generator (PMSG). The technique mentioned previously leads to a separation of the variables into dis-joined subset or two separated models: the first one has a fast dynamics, and the second a slow dynamics. Additionally, we present the mathematical model of the permanent magnet synchronous generator (PMSG) authorizing the simulation of his dynamic behavior under the MATLAB/SIMULINK environment, the model is based on the transformation of Park. Besides this work came up with the models of the rectifier with MLI control and the inverter with hysteresis control. The control speed and the Id current are realized PI regulators.
