What’s the Deal With Derivative?
What is it that derivative is supposed to help accomplish when tuning proportional-integral-derivative (PID) loops? Most of us get by most of the time with simply using the P and I components when tuning a loop. And if the loop is reasonably fast, such as a flowmeter or speed adjustment or even pressure, we can get the job done and not have to deal with derivative.
When we’re dealing with loops that have long response times such as temperature loops for tanks or dryers, there is a tendency to over-damp those loops to avoid massive overshoot of the process variable.
As an example, think about driving your car. Pretend that you are the PID loop control, the speedometer is your process variable, and the speed limit (at least in your mind) is the setpoint. If you only use P to govern how you apply the accelerator, then you’ll never reach setpoint because P needs some error in order to have an output. And since this is a linear direct proportion (gain being the proportionate factor), it is also immediately responsive. You would get a lot of accelerator when the car was first at zero speed, and then as the speed increased the accelerator would be decreased in proportion to the difference between the current speed and the desired speed (setpoint).

Food Manufacturer Improves Yields 5% With Installation Of Steam Peeler Equipment
Hata Foods is a subsidiary of the Kobe Bussan Group which manufactures frozen foods, chilled side dishes and PET-bottle products such as salad dressings and sauces.

Hata Foods has a popular product line which highlights the flavor of Japanese domestic potatoes, also known as 'Potato Salad Bases'. To help with production of this line, Hata installed a TOMRA Orbit 150 steam peeler, brusher, washer, and a TOMRA Genius B1200 sorting machine. The company's CEO Toshiyuki Hata discusses what kind of impact these changes have had.

Hello World

For most users, this is the best way to upgrade because it means your existing programs and data remain where they are. Sometimes, however, you don't want to do a regular OS upgrade. Maybe you want to start fresh or maybe you need to install El Capitan on a machine that doesn't already have OS X installed. For those users, the best bet is to do a clean installation, erasing the hard disk and installing from scratch

If you want to do a clean install of OS X El Capitan on your Mac — or on a new hard drive — you can do it, it just takes a bit of work.

If you've gone through the clean install processes in the last few years, these instructions will look familiar. (That's because they are almost the same as past years, albeit with changes made for the proper OS name). With a little time, it's relatively easy to create a bootable copy of OS X El Capitan that you can run from a USB stick or other drive.

Note: A clean install will erase all of the contents on your disk drive. Make sure to back up your important files, settings and apps before proceeding.
