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.
According to an article in BBC, underwriters at Lloyds’ of London say they have seen a "huge increase" in demand for cover from energy firms. But surveyor assessments of the cyber-defenses in place concluded the cyber defenses were inadequate. Now, compare this to the US electric industry.
Every day is somebody’s birthday or anniversary. For example, Google has a doodle up today celebrating the 112th birthday of American author, John Steinbeck. But another, in some respects more important, anniversary is coming up.
The14th ICS Cyber Security Conference (sometimes known as "Weisscon") will be held October 20-23, 2014 at Georgia Tech. Based on record attendance from last year's conference, please consider making your registration early to assure a space. Registration for the conference will be open to the general public soon.

How do you know when interaction is going to be a problem? Why would the control loop design need to be changed? Are there hidden loops? What can you do with tuning to mitigate the problem? When do you need to move on to Model Predictive Control? Hopefully, this blog...
