Course Description

291-Proportional, Integral, and Derivative Controller Design Part 1

In this course, the design and application of Proportional plus Integral plus Derivative (PID) controller's is discussed. Some familiarity with feedback control may help in providing a better understanding of the course material. PID control is a technique used extensively in feedback control systems. Its origins date back to the 19th century, being used for governor speed control, and since then in numerous applications with a wide variety of actuators and sensors. The controller is simple structure; being the sum of three terms as the name implies. The PID structure provides for a fairly wide range of tuning adjustment in a feedback control loop, especially for relatively simple processes. A PID uses the error, it's integral and derivative to derive a control signal driving the error to a null state. The controller can be structured in many configurations; P-only, PI, PD, PID, plus others to be discussed. PID control is central to most process control systems; but can also be found in numerous applications other than process control ranging from positioning control loops to pointing, tracking and platform stabilization control loops. The PID can also be integrated with higher level control strategies such as model predictive control, adaptive controllers and fuzzy logic control described in Part 2 of the course.

Starting with an introduction in section 1.0, topics covered are a description of the basic feedback control loop block diagram in section 2 and how the PID relates to the control loop. The relationships between time and frequency domain representations of the block diagram elements are discussed in section 3 followed by the key feedback relationships derived from the block diagram algebra in section 4. The PID control algorithm is described in section 5 which includes the frequency domain characterization of the PID (5.1), the effect of each PID term has on response (5.2) and finally different forms of the PID used in actual applications. In section 6 a discussion of specifying control loop performance is presented. PID control loop design methods are provided in section 7. The basic theory is applied to an example; a home heating system, in section 8.

Good introductory Course to PID Controllers, - It could do with less math and more practical applictions.

This is the LaPlace to refresh your controller knowledge; especially before Part 2.

Very comprehensive. Only request would be to put a table of terms at the beginning or end of lecture to help as a person was going through the calculations.

Comprehensive Part 1 of PID controllers. Good introduction to specifications and how P, I, D functions in various applications to provide gain and stability. Text suffers from incomplete sentences, grammatical incompatibilities, and paragraph structure. Could be better organized.
