Application of Proportional Integral Derivative [PID] Algorithms in Modern Industrial Control
Subject area: Science,Engineering and Technology · Area of research: PID controller
Abstract
A proportional-integral-derivative controller (PID controller) is a control loop feedback mechanism widely used in industrial control systems. A PID controller calculates an error value as the difference between a measured process variable and a desired set point. The controller attempts to minimize the error by adjusting the process through use of a manipulated variable. The PID controller algorithm involves three separate constant parameters, and is accordingly sometimes called three-term control: the proportional, the integral and derivative values, denoted P, I, and D. Simply put, these values can be interpreted in terms of time: P depends on the present error, I on the accumulation of past errors, and D is a prediction of future errors, based on current rate of change. This paper evaluates the use of weighted sum of these three actions as used to adjust the process via a control element such as the position of a control valve, a damper, or the power supplied to a heating element.
