Practical Control of AC Machine

Part of the Advances in Industrial Control book series (AIC)


The electric machine based on a control system with the machine model is not a simple task but requires necessary simulation tools to understand its basic operation. The complexity of their models suggests performing first simulations both in open and closed loop, without using an electric drive (VSI or DC servo stage). High-performance control, such as vector control for AC machines, can be achieved with excellent results by using suitable simulations. The machine control simulations are increasingly because represents an ideal tool to achieve extraordinary results in a relatively short time of development. This chapter deals with the speed and current loop control theory of the rotation loads by using a DC machine as an introduction of AC machine vector control. Some simulations’ results with and without electric drive are illustrated. The chapter continues with the theoretical and practical part of vector control through simulations without electric drive, as well as the practical development of magnitude and position flux observers, and estimators for sensorless systems. The most relevant AC machines on the market are covered, such as the induction machine, the permanent magnet synchronous machine (PMSM), the synchronous reluctance machine (SynRM), and its variant, the permanent magnet-assisted synchronous reluctance machine (PMASynRM).
