Abstract

Applications of the digital computers in the control systems are not new. But when one tries to integrate the control system with a digital computer to form a feedback loop, he has to solve a great deal of problems in both hardware and software aspects. Such problems are investigated in this paper. For the hardware aspect, one has to design interfaces for both ADC and DAC. Since these are absolutely necessary pieces of hardware, one can notavoid from using them. The interface which employ the programmed data transfer method was designed for this research. For the software aspect, one has to build models for the digital compensator and the controlled system. In order to do that it is necessary to utilize the real time clock and to write his own interrupt service routine. As a sample case, a deadbeat compensator was desinged and tested.
