Abstract
A process control system including a method of suppressing overshoot of a process variable beyond the process value setpoint by predicting the overshoot by observing a waveform associated with the process variable, observing the waveform associated with the process variable, without regard to time scale or to amplitude scale, taking corrective action to reduce or eliminate said overshoot by utilizing a fuzzy logic module with a proportional integral derivative control to take corrective action of the process variable.
