From the series: Field-Oriented Control of Inductance Motors with Simulink
Sabin Carpiuc, MathWorks
The video shows how to use Simscape Electrical to build a model that includes a squirrel cage asynchronous machine, a power inverter, voltage source, a power transformer, and a rectifier. The video explains how you can change parameters of various blocks in the model including motor parameters, switching devices in the inverter, and parameters of the transformer to customize the model for your application.
It demonstrates how phase currents and phase voltages can be measured from the model. It also shows how to model a mechanical load on the motor shaft. A proper choice of simulation solver is discussed to achieve the right balance of simulation speed and accuracy.
The video then explains how to model various components of a field-oriented controller. Those include proportinal-integral (PI) controllers for the inner current loops and outer speed and flux loops, Park and Clarke transforms, and space vector PWM generator, as well as an observer for estimating rotor position and speed.
