Abstract Details

1975, Master of Science, Ohio State University, Electrical Engineering.
A design of a digitally controlled environmental chamber for controlling conditions such as temperature, relative humidity and concentrations of pollutants is developed. It includes a selection of instruments, an interface circuit design for the computer, a methodology for the determination and evaluation of critical constants used in a Proportional, Integral and Derivative (PID) control algorithm (selected as the process control technique) and a basic programming procedure for operating the system. The system design is meant to be flexible and representative in nature. Extended capabilities of the system include the possible addition of other control loops, further refinements in programming and a compatible data handling system.
