PID for dummies


Thread Starter

Tom Holderfield

Can anyone steer me in a direction for info about PID loops? I know very little about PID's, but can do standard programming.
Visit the web site of Micon
Obtain their booklet, it's a mine of informations for Process Control Instrumentation.
One of the better and inexpensive books on this subject is David W. St. Clair's book "Controller Tuning and Control Loop Performance - PID Without the Math." This is a ~90 page book which costs, last I heard, $16 plus postage. There is a companion software($10) that allows you to play with PID loops. You can order the book and software from:

Depending on how much you want to learn and if you have any money at all to spend on learning it, we have a training package (PC based course including simulation of controllers and processes). More description can be found at check LearnWARE process control basic.

I am an aspiring PLC programmer who was recently laid-off and may have a chance for a new job, if I know anything about waste water process control.
PID was mentioned at interview. Please help if you are so kind, maybe knowing your method will get me started.
