The introduction of microprocessors into electric vehicles has opened many interesting possibilities for improving the operation and maintenance of such automotive systems. On the other hand, microcomputer-based motor control systems are playing an ever increasing role in research on applied electronics. In this paper, a microcomputer-based digital dynamic control system (DDC) for a de motor is described. The description includes motor identification and corrector digital implementation, as well as precision analysis of the control system. The influence of poles and corrector gain on the system response is also presented, this allows the choice of appropriate parameters for the design of a lag-lead controller. The application of such a controller with a low power dc motor verifies the theoretical approach and reveals the necessary information to analyse the speed control system stability of a chopper-fed de motor using the same controller.
