Abstract
Conference Title: 2014 International Conference on Information Science, Electronics and Electrical Engineering (ISEEE) Conference Start Date: 2014, April 26 Conference End Date: 2014, April 28 Conference Location: Sapporo, Japan 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.
