A precision closed-loop dc motor control system is developed that could be used to control the position of a radio telescope. National Instruments (NI) Data Acquisition (DAQ) Board (Model MIO 6040E), LabVIEW software package, and DAQ signal Accessory Board have been employed for smooth and accurate motor positioning. The motor circuit is designed for clockwise (CW) and counterclockwise (CCW) rotations. A synchro system is used to provide current position of the motor. The control of position and direction of the motor is via a power transistor (TIP 41) and two pairs of relays (RL11 and RL22) connected between the motor and the output port of the ...
