PERIODO: GENNAIO 2017

Il corso sarà tenuto dal Prof. Marko Hinkkanen della Aalto University - Finland

Introduction: This course deals with model-based control in electrical energy conversion. Synchronous motor drives and grid-connected power converters will be used as application examples. Many advanced control methods, such as state feedback control, are widely applied amongst control engineers. However, they are considered too complicated to be applied in electrical drives and power con-verters. This is not true: state feedback controllers can be easily (or automatically) tuned and their computational efficiency is comparable to that of PID controllers. The main contents of the course are:

• Energy conversion: fundamentals, synchronous machine models, power converters, vector control
• Modeling concepts: space vectors, state-space models, transfer functions
• Control design: model-based PI control, state feedback, pole placement, observers, nonlinearities, discrete-time models
• Parameter identification: selected examples
The control perspective is taken in this course, but physical models of example systems and applied modeling concepts are also covered.

Prerequisites: The course is targeted to PhD students and advanced master's students in electrical and control engineering. Prior knowledge of power-electron-ics converters, three-phase systems, and vector control principles is preferred.

Material: Lecture slides and computer assignment instructions will be provided as PDF files during the classes. Some scientific articles are also used in the prelimi-nary assignment, as described lated.

Preliminary schedule: Classes at 9:00–13:00 from Monday to Friday. These classes include also some hands-on MATLAB exercises. The lab is equipped with desktops. If preferred, please take your own laptop with you.

Requirements: To pass this course, you must satisfy the following requirements:
• Preliminary assignment: Read the following papers before the course:
◦ J. Kukkola, M. Hinkkanen, K. Zenger, "Observer-based state-space cur¬rent controller for a grid converter equipped with an LCL filter: analytical method for direct discrete-time design," in IEEE Trans. Ind. Applicat., vol. 51, no. 5, pp. 4079–4090.
◦ M. Hinkkanen, H. A. A. Awan, Z. Qu, T. Tuovinen, and F. Briz, "Current control for synchronous motor drives: Direct discrete-time pole-place-ment design," IEEE Trans. Ind. Applicat., vol. 52, no. 2, pp. 1530–1541.
◦ D. Perez-Estevez, J. Doval-Gandoy, A. G. Yepes, and O. Lopez, "Posi-tive- and negative-sequence current controller with direct discrete-time pole placement for grid-tied converters with LCL filter," IEEE Trans. Pow. Electron., early access.
◦ M. Hinkkanen, P. Pescetto, E. Mölsä, S. E. Saarakkala, G. Pellegrino, and R. Bojoi, "Sensorless self-commissioning of synchronous reluc-tance motors at standstill without rotor locking," IEEE Trans. Ind. Appli-cat., accepted.
Try to understand what is the core content. Detailed knowledge of the pa¬pers is not required. Prepare a brief question (or a comment) about each paper. For example, explain what was difficult to understand or what would you like to know more. Send the questions and comments to Marko Hinkkanen no later than on 6th February. The estimated student workload of this preliminary assignment is 20 hours.
• Class participation: Students are expected to participate classes. The esti-mated student workload is 4 x 5 = 20 hours.
• Simulation assignments after the course: Recap the material and complete the simulation assignments (separate instructions will be provided). The es-timated workload (including recap) is 30 hours (depends on ECTSs).
