Multiple Loop Control (AIP02)

Learn the principles of multiple-loop control strategies to industrial process control systems.

Prerequisites

This lesson is designed for participants familiar with single-loop control. An understanding of pressure, temperature, level, and flow measurement, as well as basic algebra, is also recommended.

Description

This lesson explains the application of multiple-loop control strategies to industrial process control systems. The lesson also explains the operation of several types of digital process control systems.

Objectives

Identify the benefits of advanced process control strategies. Compare feedback and feedforward control. Explain the principles and applications of a feed forward control system. Explain the principles and identify the benefits of cascade control. Discriminate between wild and controlled flows in a ratio control system. Explain the principles and applications for ratio control. Explain the principles and application of adaptive and selective control. Identify the method of process control used in direct digital, supervisory, and distributed control systems.
