Subject description

Prerequisits:

  • Matriculation.
  • Basic knowledge of electric machines, electrical drives, power electronics, control engineering and microprocessor techniques is expected.

Content (Syllabus outline):

The overview of methods and procedures for control of modern servo drives with AC machines: induction, synchronous (with surface-mounted and buried magnets) and reluctance machines. Controlled drives in mechatronics (speed control in current supplied electrical machines; field oriented control – FOC; direct torque control – DTC). Problems concerning robustness of the control considering incorrectly identified and/or fluctuating parameters of the drive. Position and/or speed sensorless methods in AC drives. Sensorless control. The application of observers and MRAS in servo drives. Application of modern microprocessors in dynamically demanding electrical controlled systems: tasks, problems, configurations, software. Electrical drives with linear motors and their significance in industrial applications. Electrical drive systems in automotive vehicles (primary and auxiliary drives). Electrical traction systems – supply and drive principles, high speed applications, magnetic levitation systems, trends. Double fed induction machine in wind energy conversion systems and pump power plants. Design principles of energy efficient electric motors, control of electrical drives in energy saving regime. On-line condition monitoring and diagnostics of electrical drives, early detection of electrical and mechanical faults of AC motors and power converters, application of artificial intelligence methods in integrated approach to control and supervision of modern servo drives.

Objectives and competences:

Students will be acquainted with the latest approaches and tools for open- and closed-loop control, monitoring of electrical servo drives and future trends in this research topic.

Intended learning outcomes:

Students will be able to asses the parameters of the entire drive system (control part, power converter and motor) and evaluate the priorities in choosing the appropriate configuration complying with the commission. The acquired knowledge will enable further investigation and application of new solutions in wide area of mechatronics.

Learning and teaching methods:

Lectures and individual student work with a mentor during preparation of the seminar work on a focused research topic.
