Pre-defined Courses | On-site workshops | Scheduled Workshops at Conferences
The following two popular courses, or slightly modified contents are frequently taught at leading industrial conferences. Duration of each course is for 4 hours including mid-break.
Course #1: Basic Principles of DC, Brushless and Other AC Motor Control ( Half-day)
This introductory course is to provide fundamental concepts of motor control. The objective of this course is for motors & drive designer, application engineers as well as marketing and management professionals who want to learn fundamental principles and basic knowledge on electromagnetic torque production theory, construction and operation of DC, PM brushless, Switched Reluctance, and Induction motors. This course also discusses about basic principles of feedback control and servo systems, PID regulators and their tuning procedure.
The course starts with the magnetic and mechanical structure of the various motor types (including DC, induction and SR motors) and feedback devices to understand torque production mechanism and required commutation logics. Discussion is followed by control of power semiconductor switches, PWM, motor drive topologies, drive hardware, control algorithms, and software implementation, as well as current and speed control. The content also explains pros and cons of drive technologies such as 6-step vs. sinusoidal, voltage drive vs. current drive, phase current regulator vs synchronous regulator, PID vs other controllers, sensored vs sensorless control, etc. From the author’s long experience in research and development of many different types of drives, practical and useful procedures in selecting control method, rule-of-thumb design rules, control system structure and tuning, performance vs. cost tradeoff, etc will be discussed.
Course #2: Field Oriented Control and Advanced AC Motor Control Algorithms (Half-day)
This course will provide in-depth knowledge and skills in control algorithms and software to design 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 brushless motor control theory & PID control as outlined in Course #1.
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 energy efficiency including Predictive current control, Space Vector Modulation, Field Weakening operation, Sensorless control technologies, and Switched Reluctance motors. At the end of the course, the course will have an interactive discussion about special topics that might be of interest to the audience.
