Advanced Control Technologies for AC/DC Motors & Drives
Presented by Dal Y. Ohm, Ph.D., Consultant, DriveTech
When: Monday, February 7th; 1:00 pm to 6:00 pm
Cost: $550
This course is to provide fundamental concepts of electric motors and motor control systems, and introduce advanced control technologies practically in use. Course content includes control electronics hardware and AC/DC motor control algorithms, servo system feedback control, PID regulators and their tuning procedure, and motion profile. The course starts with the magnetic and mechanical structure of the various motor types (including DC, PM, IPM, Induction and SR motors) to understand torque production mechanism and required commutation strategies. Discussion is followed by control of power semiconductor switches, PWM techniques, motor drive topologies, drive hardware, control algorithms, 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. Aldo included are sensorless control and flux weakening controls. From the author’s long experience in research and development of many different types of drives and controls, 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.
Dr. Ohm is a technical consultant specializing in motor control, drives and renewable energy converter systems. He has more than 30 years of industrial and academic experience in research and product development in the fields of motor drives, servo systems, and power converters. His major area of interest includes motion control, digital control, high power AC and DC motor drives (Sensored and Sensorless) and power electronics. He has more than 80 published articles and conference presentations in the above area. Prior to consulting, he was President of Drivetech, Inc., Technical Director at Kollmorgen Motion Technologies Group. He was also with Baldor Electric Company and Electrocraft, Inc. He taught engineering courses (Electric Machines, Robotics, Digital Control) at San Jose State University, NPU, and Cogswell Polytechnical College as Adjunct Professor for many years. He received Ph.D. and M.S. degrees in Electrical Engineering from Texas A&M University. He is a member of IEEE and MCMA.
Magnetics Bootcamp
Presented by Dr. Stan Trout, Spontaneous Materials
When: Monday, February 7th; 1:00 pm to 5:00 pm
Cost: $550
The Magnetics Bootcamp focuses on teaching you the basics of magnetics with an emphasis on permanent magnets. If you need to understand magnets better for your job, want to understand the conference presentations, or are new to the field, the Magnetics Bootcamp is the perfect place to start. It assumes that one has little or no background in magnetics. The Bootcamp will cover all the essential fundamental magnetic concepts such as hysteresis, the nature of magnetism, units, magnet processing, magnetizing, measurements and thermal effects.
With over forty years' experience in the permanent magnet and rare earth industries, Stan has a wealth of problem solving abilities, gained from a wide variety of technical and commercial roles, that he is eager to share with his clients. He has been very fortunate to confer, study, meet and collaborate with many international luminaries along the way. He is particularly proud to have trained many of today's active industry professionals. Stan has a B.S. in Physics from Lafayette College and an M.S. and Ph.D. in Metallurgy and Materials Science from the University of Pennsylvania. Dr. Trout is a registered Professional Engineer in both Colorado and Pennsylvania.
