EGSA on-peak performance
2012 Articles
Founded in 1965, the Electrical Generating Systems Association (EGSA) is the world's largest organization exclusively dedicated to On-Site Power Generation. EGSA is comprised of 700 companies around the world that make, sell, distribute, and use On-Site Power generation technology and equipment, including generators, engines, switchgear, controls, and much more.
The Association's vision is to provide an environment where On-Site Power Generation industry experts unite and share knowledge to drive the industry to higher levels of service and performance.
Self-Tuning Controllers Auto-Select P, I, D Values
Tuning a PID controller is conceptually simple--observe the behavior of the controlled process and fine tune the controller's proportional (P), integral (I), and derivative (D) parameters until the... » more

Intrinsic safety protects your plant against explosions
Explosions can be prevented by limiting the amount of electrical energy available in hazardous areas or by containing the situation using bulky, heavy devices called 'explosion-proof enclosures.'... » more

Overcoming the deadtime dilemma
Arguably the trickiest problem to overcome with a feedback controller is process deadtime--the delay between the application of a control effort and its first effect on the process variable. During... » more

Bode plots solve frequency domain problems
Every child who has ever held a spring upright knows that tugging on the top end causes the bottom end to start bouncing and that repeated tugging keeps those oscillations going. Some may notice that... » more
