PID algorithms
I do not know what is meant by the "Ideal" form. In the time domain, the parallel form is the simplest: output = Kp x ( e + Ki x Integral( e dt) + Kd x de/dt) where Kp is proportional gain, Ki is reset rate in repeats per minute, and Kd is derivative in minutes. The series form...- johnshaw

PID algorithms
Thus ask dinjag: >With digital control technology, several different variants of PID >algorithms have proliferated. Is there any reference (book, article or website) where >these algorithms have been compiled? You might check my web site, http://www.jashaw.com/pid I have a tutorial on the PID...- johnshaw
