Overview
This course examines a particular control structure that has become commonly used in industrial control. It is based on a particular fixed structure controller, the Proportional, Integral, Derivative (PID) control. These controllers have proven to be robust and extremely beneficial in the control of many process applications. Applications include variable-frequency drive, temperature, pressure, flow, and level controls which are widely used in modern industry. The method is most useful when a mathematical model of the process or control is not available.
The course starts by introducing the basic theory behind PID control. Then, it is followed by two major types of controls: open-loop and close loop controls. Tuning the three constants in the PID controller algorithm is a very important concept of any PID application; therefore, PID tuning will be focused. Examples will be used throughout the course for engineers to understand the steps to implement and tune PID controllers.
It is my intention that this course will help you understand how most PID controllers work, which will provide you the basic knowledge to perform the task.
The student must take a multiple-choice quiz consisting of twenty (20) questions at the end of this course to obtain PDH credits.
