DC MOTOR CONTROLLER DESIGN FOR TRACKING ANTENNA SYSTEM BASED ON CVBS ANALOG SIGNAL PROCESSING
DC motor is often used in tracking antenna system. Generally rotation of the motor is controlled manually by using the remote control. To be able to rotate automatically, then the tracking antenna system requires compatibility between input parameters with decision making process. Thus, the ability of auto tracking on tracking antenna system can be achieved. In this research, DC motor controller is designed as an effort to build the tracking antenna system which has auto tracking capability. In the design, the input parameters are obtained from analog CVBS signal processing. Results from the processing yield 2 parameters, among other are Composite rising transition and Vertical rising transition. Characteristics of both parameters are used as a reference in the decision making process. The trial results show that the DC motor controller has been designed to produce minimum tracking time of 1.6 second and maximum 115.2 second.
