Field Oriented Control of Induction Machines — Lesson 3

This lesson covers the steady state terms and their disturbances, and how to remove the effect of the steady state terms. It further elaborates on the expression for small signal inputs given as disturbances and the response. The lesson explains the state variable notation and its usefulness for further simplifications. It also covers the flux linkage in the stator coil. Towards the end, the lesson discusses the concept of field-oriented control of the induction machine and encourages learners to explore more about it from the literature.
