The project is to design a controller for positioning a mechanical rotating platform based on position commands. The mechanical platform can be moved in both azimuth and elevation angles. The platform consists of DC motors, associated drive circuitry, encoders and brake for the motors. In this mechanism, the command is received through the serial communication channel from the external system. In the platform, after disabling the brake and applying some control voltage, the platform starts rotating for positioning. Simultaneously the counter starts counting the pulses. After some degrees of rotation, the speed is increased to maximum by increasing the control voltage and the speed is decreased when the platform seems to attain its desired position. And then, when current position equals to the desired position, the brake is enabled by removing the applied voltage signal. Then the position feedback is sent through the serial channel.
