CHBE 470: Process Dynamics and Control

Syllabus

**Course
Objectives**

Learn the scientific and engineering principles underlying
process dynamics and control

Apply and integrate knowledge of chemical engineering to identify,
formulate and solve process control problems

Use and apply modern computational techniques and tools for
solving chemical process control problems

Become familiar with industrial control systems

**Course Content**

This course will cover the theory underlining the practice of process control and its applications in the chemical processing industry. As such, it will be both analytical and synthetic in nature. The following is a brief outline of the topics that will be covered.

** Introduction to Process Control**:
Incentives for chemical process control. Feedback and feedforward
control configurations. Design of controllers.

** Mathematical Tools**: Mathematical modeling
of dynamic processes. Linearization of nonlinear systems.

** Response of open-loop systems**: First-order
systems, second-order systems, higher-order systems, time delays, inverse
response systems, transfer functions.

** The control system**: Components of a
control loop. Closed-loop transfer functions. Transient response of simple
closed-loop control systems. Types of controllers. Stability of controller operation. Frequency
response methods. Nyquist Stability Theorem.

** Design of control systems**: Feedback
control. Feedforward control. Cascade Control. Multivariable
control systems.

**Homework**

Unless otherwise stated in class,
the assignment will be due **in exactly one week** **at the beginning of
class**. Late submissions of up to one day will receive 50% credit. No credit
will be given for homework submitted more than one day late. Please write
concisely.

** Regrade
Policy: **Requests for regrades on
tests or assignments will be accepted only if submitted to the course
instructor within two working days after the test or assignment is returned. In
such a case, you should submit the original and a separate signed page
describing exactly what is disputed.

**Grading Standards**

**A**: achievement that is outstanding relative to the
level necessary to meet course requirements

**B**: achievement that is significantly above the level
necessary to meet course requirements

**C**: achievement that meets the course requirements in
every respect

**D**: achievement that is worthy of credit even though it
fails to meet fully the course requirements

**F**: represents failure and signifies that the work was
either (1) completed but at a level of achievement that is not worthy of credit
or (2) was not completed and there was no agreement between the instructor and
the student that the student would be awarded an I.

**I** (Incomplete): Assigned at the discretion of the instructor
when, due to extraordinary circumstances, e.g. hospitalization, a student is
prevented from completing the work of the course on time. Requires
a written agreement between the instructor and the student.

**Honor Code Policy**

Students are encouraged to talk with each other, TAs, the instructor, or anyone else about any assignment in the course that is not specifically designated "pledged." This assistance is limited to a discussion of the problem and perhaps a sketch of the solution. Consulting another student's solution (even from a previous CENG 470 class) is prohibited. Moreover, submitted solutions may not be copied from any source.
