    yes that's right proportion integral derivative controllers.. can some one tell me why? Man it took me about 6 hours of research to finally figure them out and the application I use them for at the plant. But why, WHY is everything in a foreign language? And by that, I mean words explaining a process needed to be looked up and understood before I could understand the process because I didn't understand the words explaining the process.. but it was fun learning :confused:

  3. You seem really wound up. I think your integral gain may be a bit high!

    And what does a PID controller do? It took me four weeks to figure out why we had two $75,000.PLC's,installed. When one dedicated unit the size of an office fridge,would have done an even better job of handling the electrical distribution, and the data processing. The only reason turned out,was to eliminate jobs, by having management control the melt process from the supervisors office. Things went south a few months later when they hired a college graduate from Princeton, a Ukrainian on a student visa, he corrupted all of our systems, by running an online simulation, that had a hidden Trojan virus. The melt furnaces never ran properly after wards. Then the plant was closed without notice.
     
  5. A PID controller is what allows you to control a process at a given set point. Think temperature control, speed control, level control, pressure control, etc. What if your furnace, instead of turning on and off within a couple of degrees of your desired temperature, the furnace would always be running and the gas to the burner was automatically increased or decreased to maintain a more precise temperature even if maybe a door was continually opened and closed.

    I think people who write operational texts are insecure so they try to impress their bosses and screw the people that actually need the manual.

    Now I get it. Thanks. Used to put those together, back then known as programmable controls.worked six years as mechanical line gang.our job was to make the boxes,essentially dummy proof! Then our suppliers, started to sell the pre-made boxes. Cutting crew sizes in many departments.

    I was always proud of my work,at that time. You get a certain feeling from start to finish, most only see one portion of a product.

    That tells me a lot about you. I'm always proud of my work too and get seriously insulted when in question.

    Integral gain is a false

    When I first started using a computer for work my buddy, an IT guy, set me up with a home PC. I asked all kinds of questions wanting to know the answers to everything. He told me to just play with the thing and I'd figure it out for myself.

    He also said that the one thing that would trip me up would be the jargon! A lot of it is impenetrable.

    Also, at one time, if you were studying engineering in the U.S. it was also recommended that you study German since so many engineering papers came from there.

    Just funning with ya cause you wrote, "But why, WHY is everything in a foreign language?" Reminded me of when buying most anything these days, you get a one-inch thick manual in 9 different languages or when you call a company's customer support lines, you have to listen for five minutes to a recorded message, in four languages, how to press the number 'ONE!'

  19. Quality is no longer important. Quantity is what is important now. But, they still preach Quality but really dont give a ****. I am truly disgusted with today's Corporate world. I am nothing but a Binary number in some computer program.

    My father's friend,was a quality control rep, in Japan,back when everything was made in Japan. He wasn't pleased by the lack of respect by the factory,and it's policy to,only allow him access,in 30 minute increments, boils down to twice a day. He made good money, but was never home, he passed away while in Hong Kong. He was only 40years old. He was someone that could make any one laugh.
