Modeling and simulation of the VVVF control of the three-phase AC asynchronous electromotor based on Matlab/Simulink

The mathematical model regarding three-phase AC asynchronous electromotor is a high-order, nonlinear and strong-coupling system with multiple variables. It is thereby relatively knotty to control its rotation speed and flux linkage effectively due to its complex dynamic and static properties. For these reasons, it is a desideratum to decouple and optimize the model of an asynchronous electro-motor. In this paper, we will achieve the model's partial decoupling by coordinates transforming and the mathematical model vis-à-vis the AC asynchronous electromotor depending on Variable Voltage and Variable Frequency (VVVF) control.
