Register for both DriveTech workshops: $650
This course will provide in-depth knowledge and skills in control theory, algorithms and software structure to design various high performance AC motor drives and control systems. The course is intended for experienced engineers who have prior exposure in motor drive design, or have basic knowledge in DC and AC motor control theory & feedback control theory as outlined in the morning workshop, “Overview of Basic concepts and technologies on Motor Drives & Motion Control”.
The course starts with the basic principles of FOC (Field Oriented Control, aka Vector Control), reference frame transform theory, and dynamic motor model of PM motors and induction motors. Then the discussion continues in applying the FOC principles to PM synchronous motors, IPM, and Induction motors. Discussion is followed by various advanced motor control techniques for high performance and high energy efficiency including Space vector Modulation, Field-weakening operation, and Sensorless control algorithms. The last part of this course will be dedicated to additional topics of interest from participants, such as other advanced control methods or control of special motor types (such as Reluctance motors), Other applications of FOC concept (like Generators, Inverters, and Active Rectifiers), Modeling and Simulation, etc.
The course material is heavily modified and enhanced with many new topics from past similar courses by the lecturer.
