IEMDC Tutorial

Prof. Gianmario Pellegrino and Prof. Radu Bojoi presented a tutorial al the IEMDC conference 2019 about "Control of AC Drives: from Theory to Implementation"

Abstract

The demand for premium energy efficiency and the challenges of transportation electrification have drawn the attention on advanced, variable speed electric drives (eDrives). Today, there are many custom eDrives solutions, employing different control algorithms. Implementation-wise, engineers within the industry are facing many challenges to put in production eDrives. In addition, the eDrives must be properly tested to validate their performance towards the application requirements, since the nameplate data and the rated parameters declared by the suppliers are very often insufficient to this purpose.
The tutorial is addressed to engineers involved in industrial R&D and within the academia. The tutorial provides an overview of AC drives control techniques, including vector control and direct flux and torque control. Different AC machine types will be covered, including Induction Motors (IM), Surface Mount- and Internal- Permanent Magnet (SPE and IPM) machines, and Synchronous Reluctance (SyR) machines.
The electrical motor (eMotor) parameters and power converter current and voltage limits will be translated into optimal control trajectories such as the Maximum Torque Per Ampere (MTPA) and Maximum Torque Per Volt (MTPV) regions.
The tutorial will present results from experimental cases and provide simulation models.
