Abstract
A real time microcomputer controller, based on a mature algorithm, was implemented for the speed control of a D.C. motor. Control algorithms were developed for both an inner current loop and outer speed loop, using classical control design techniques. These provided the necessary compensation for system stability to a step response. All control functions were implemented through an 8 bit microcomputer. A digital speed reference, coupled with speed and current feedback signals were the prime inputs. An assembler program provided the necessary compensation and switching logic. It also generated real time trigger pulses to fire the S.C.R. bridges. A prototype system was built to test system response characteristies and the actual performance of the controller under operating conditions were demonstrated.
