OptoForum member tohox recently posted a question about using PID control loops on a SNAP-PAC-R1 rack-mounted controller.
The issue? A really long dead loop time.
"The time delta between the moment the strategy opens a given loop's valve [and] starts the pump+furnace and the moment a temperature increase is measured can sometimes be on the order of an hour," tohox notes.

Tasty and wholesome, the frozen fruit bars made by Natural Fruit Corporation must be stored at precise temperatures.
Although their cold storage rooms were automated, on weekends operators used to have to stop by the company's factory to verify that systems were running and temperatures were within range.

If you live just about anywhere in the U.S.A., you can probably thank California Controlled Atmosphere (CalCA) for some of the fresh fruits and vegetables you buy.
In fact, CalCA's industrial refrigeration systems for storing produce can be found throughout the world, reaching to India and China.

As "green" power production from sun and wind increases, electrical grids can find themselves with a big problem: too much electricity at once.
Solar and wind power generation work when the sun shines and the wind blows. But those hours are not necessarily when electrical demand is highest.

In automation, proportional integral derivative (PID) control loops are common, useful, and tricky to get right.
Each loop is different and each requires individual tuning for maximum effectiveness.
Now here's a new tool to help you tune your PID control loops: our online PID Control Loop Tuner.
