Working with Controllers

Covers the purposes and kinds of controllers and their relationship to other components in process control systems. Explains the concepts of current-, position-, and time-proportioning control. Compares the operation of several kinds of controllers. Describes the operation of proportional, integral, and derivative modes, and discusses tuning procedures for each. Discusses cascade, feedforward, ratio, and auctioneering control systems as well as other operations. Describes ways to eliminate or reduce controller problems. This course has no prerequisites. Working with Controllers is available in online technical training and course manual formats. Lesson 1 - Introduction to Controls Topics: Process dynamics; Current, position, and time proportioning; Controller modes, actions, terminology, and options; Loop accuracy Learning Objectives: – Describe the kinds of controllers most often used in industrial applications. – Discuss six important problems of pr
