ADVAVANCED REGULALATORY CONTROLL

12.1INTRODUCTION

The power of the proportional-integral-derivative (PID) largely remains underutilized. Most of the options and parameters other than scale ranges and tuning settings remain at their defaults. Here we look how to tap into the incredible capability of the PID to minimize batch cycle time and startup time and to maximize production capacity, flexibility, and efficiency while reducing disruption to utility, raw material, and reagent systems. Also detailed is a simple method to compensate for dead time and to eliminate limit cycles.
