Given that cascade control loops are everywhere without much consideration as to dynamic requirements, what can we do to make the implementation effective? Here are some specifics by the way of detailed recommendations on the sequence, speed, and setup for tuning PID and digital valve controllers.
I have been invited to give a lecture on ICS Cyber Security at the Naval Post Graduate School April 3rd in Monterey on control system cyber security. The presentation will be similar to my presentation at West Point.
Republican House Speaker Joe Straus has tasked the House Committee on Homeland Security and Public Safety with investigating deficiencies in safety, risk management, and disaster planning at chemical facilities.
I reviewed the Bipartisan Policy report and then had a chance to meet with one of the project leads to discuss some of my concerns. The concern about cyber security of the electric grid is grid reliability.
MEMS technology has grown from a niche application industry to a US$12B industry in a little over the decade – largely driven by the consumer market however work on multiple fronts will bring this technology into the controls and automation realm in a significant way.
I have been invited to give a lecture on ICS Cyber security at West Point April 8th on control system cyber security. The presentation will address what is control system cyber security, how is it different than IT security, what has actually occurred recently, and examples of what is being...
Integrated project management and electrical/automation systems promise to change the work habits of control engineers.
Did you know all loops today use cascade control? Do you understand how cascade control can correct for lower loop disturbances before they affect the upper loop and can make the upper loop faster? Do you know what to do to keep the system from oscillating if the lower loop...
Understanding the size and scope of the automation sector is worth understanding on a periodic basis. This 4 minute video has a look at this information from several angles.
Don't worry Sten Corfitsen and his business partners are doing something to save the human race. They have invented a fully automated, robotic refueling unit for cars.
