Introducing
Cecil L. Smith, PhD, PE
Instructor for PID
With over 35 years experience in process control, Dr. Smith's expertise
encompasses virtually every control technology being applied in industrial
production facilities. In continuous processes, he has worked with oil
refining, pulp/paper, power generation, and ore processing. In batch
processes, he has experience with both single-product processes (such as PVC
reactors and pulp digesters) and the multi-product (flexible batch) processes
that are the norm in the specialty chemicals and similar industries. His
primary focus is on designing a control strategy for a process and then
commissioning the controls, that is, the process aspects as opposed to
systems aspects. However, he is proficient with both DCS's, PLC's, PC-based
controls, and single-loop microprocessor-based controls, and is capable of
resolving both process and system problems.
Dr. Smith has equally extensive experience in teaching continuing education
courses for practicing engineers on various aspects of process control and
instrumentation. He currently offers courses on the following topics:
- Automatic Process Control (focus is on loop tuning and trouble-shooting)
- Advanced Process Control (or going beyond single-loop control)
- Distillation Control
- Model-Predictive Control
- Control of Batch Processes
- Basic Measurements (flow, temperature, pressure, level, and density)
- Discrete Measurements and Control (applications; not PLC programming)
Dr. Smith's current priority is developing the Process Control Professional
Education Series to present the above topics in a computer-based format. The
challenge is to use new technology to do a better job than the conventional
approach. The Process Control Professional Education Series is a ground-up
development that couples computer-based training (CBT) technology with two
powerful simulators (both developed by Dr. Smith specifically for the
educational environment) to provide the premier educational product in
process control. The Process Control Professional Education Series will
eventually encompass all of the courses listed above.
