Developing an Open Architecture and Intelligent System for Speed and Direction Controlling (PC-SDC) of DC Motors

This paper presents a practical PC-based speed and direction controller (PC-SDC) for controlling DC motors. Developing PC-SDC is dependent on open architecture and intelligence features. Open architecture feature refers to apply the same firmware components of this PC-SDC with different types of DC motors and sensory systems. Intelligence feature is achieved by applying the collect-process-decide-deliver-instructions (CPDDI) model. The suggested CPDDI model is the real software implementation of moment perspective of a new intelligence model called “Accumulative Intelligence”. CPDDI can control DC motor via bi-directional communication channels with two practical in-house designed firmware systems. The first system is μC-based feedback speed monitoring module (FSMM) system which collects speed data (i.e., pulses count) for this DC motor by using a PIC μC-based encoder sensory system. The second system is μC-based motor control module (MCM) to control this DC motor via different intelligent rules. These rules control DC motors according to previous moving state and next required moving state. Real-time feature is investigated via two performance metrics; ART and SMT. Also, the effectiveness of the proposed PC-SDC system is investigated by a comparison between pulses count that is measured practically by FSMM system and real pulses count that is gathered from an oscilloscope.
