Abstract
This thesis describes the use of a valve control station simulator panel in developing digital computer control algorithms for process control applications. The control station panel is used in conjunction with an analog computer and a microprocessor-based microcomputer system to provide a convenient means for developing control software in a laboratory environment.
The valve control station simulator contains electronic circuitry that models a valve actuator. This actuator can be controlled either manually or by the microcomputer system. The analog computer is used to synthesize real-time process loop transfer function models, whereas the micro-computer system is used to control the loops. Digital and analog data can be input, output, and displayed for analysis.
This thesis also presents the development and application of three control algorithms that are used to demonstrate the utility of the valve control station simulator. These algorithms include a simple floating, a proportional floating, and a proportional-plus-integral-plus-derivative controller. The results of programming these algorithms on the microcomputer system and applying them to operate the valve station simulator are presented.
