    Course Description

    Basic concepts of feedback control, process dynamics, process controllers (PID)including tuning, control loop stability, cascade, ratio, selective, override, feedforward, and multivariable control. Not available for chemical engineering students.

  3. Justification

    A. Please briefly explain why it is necessary and/or desirable to add this course.

    This course is required for the Chemical Process Engineering Certificate. Chemical Engineers are educated in the design and operation of chemical processes. However, there are many other degreed-professionals (electrical engineers, civil engineers, indu

    B. What is the need or demand for this course? (Indicate if this course is part of a required sequence in the major.) What other programs would this course service?

    This course is the fourth course required for the Chemical Process Engineering Certificate. The course will not service any other program. It is estimated that the course will be offered once a year with 20 students.

    C. Has this course been offered as Selected Topics/Experimental Topics course? If yes, how many times?


    D. What qualifications for training and/or experience are necessary to teach this course? (List minimum qualifications for the instructor.)

    Ph.D. in Chemical Engineering

  4. Other Course Information

    A. Objectives

    The objective of this course is to present the basic principles of chermical process control and its practice.

    B. Learning Outcomes

    1. To know why automatic process controls are important.

    2. To know the use of the three basic components – sensor/transmitter, controller, and final control element – of a control system.

    3. To explain the concept of Feedback Control – advantages and disadvantages, – and the three operations – Measurement, Decision, and Action – of a control system.

    4. To explain the significance of open-loop transfer functions, and to draw block diagrams.

    5. To explain the differences between first-order and higher-order systems, and how the higher order systems develop.

    6. To know the meaning and significance of Process Gain, Process Time Constant, and Process Dead Time. What is the importance of these terms, and what they describe.

    7. To know the meaning and to explain the significance of process nonlinearities from a controls point-of-view.

    8. To know what is involved in obtaining a process response from a step test in input, and to approximate the response by a first-order-plus-dead time, and estimate the process gain, time constant and dead time.

    9. Controllers

    a) To select the action of a controller

    b) To know and explain the advantages of P, PI, PID, and PD controllers

    c) To know the meaning of ultimate gain and to explain how each type of controller affects it.

    d) To explain the meaning of offset, and reset-windup, and why they occur.

    e) To tune feedback controllers.

    10. To draw closed-loop block diagrams by “just looking” at a process.

    11. To know and explain the stability of a simple feedback control system. To define and explain the meaning of the characteristic equation, and how to calculate the ultimate gain and ultimate period. To know how each term of a control system affects its stability.

    12. To design control systems for simple processes.

    13. To design cascade, ratio, selective, override, feedforward, and multivariable controllers.
