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 scaled 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 correctivc action of the process variable.
La présente invention concerne un système de commande de processus industriel dans lequel un procédé permet de supprimer le passage d'une variable de processus au-delà d'une valeur de processus prédéterminée. Le système prédit le dépassement en observant une forme d'onde associée à la variable de processus, indépendamment de l'échelle des temps ou des amplitudes, en prenant des mesures correctives afin de réduire ou d'éliminer ce dépassement à l'aide d'un module de logique floue qui fait appel à une commande par dérivée intégrée proportionnelle pour corriger la variable de processus.
