Abstract : Advances in digital computer technology have led to employment of the computer as a control device. Although many theories for utilization of the digital computer as the compensator in a position feedback control system have been proposed, there is little documentation of digital control performance in a hardware environment. This thesis is an investigation of the performance of a real system under sampled-data control. The variable gain amplifier sampled-data control theory is first simulated and then tested on a real system. The hardware and software developments necessary for implementing this control theory are discussed in detail. Additionally, this method is incorporated in a time-sharing computer program for controlling many systems simultaneously from a single computer. Results of the tests are presented and evaluated.
