Abstract

Smart motor controller is build to produce a prototype for close-loop control system. The application of this project is as to resolve the problems facing by the industries and as replacement the pneumatic system operation for such a restricted place and for the short distance track conveyer. This project includes the knowledge of PIC program and the combination of controller circuit, such as the motor speed controller and the sensor. Types of motor used are the stepper motor and the detectors of sensor used are the ultrasonic sensor. Stepper motors are a digital motor that move accurately according to the degree of the rotation after it was set by the motor controller circuit. The project operations are more on the differential control and the movement efficiency with the sensor and the programming control. The motor can move forward and reverse. If they are an obstacle, it will stop after the sensors sense the obstacle more than 10 meter. They will stop at each set point the have been set the by programming in the microcontroller. From the output analysis result, variable resistor on the speed controller circuit proportional· with time (R oo T) and inverse with motor speed (R oo 1/motor speed). Other than that, stepper motor will move imitate by degrees after receive pulse from motor driving circuit about 7.5° per step.
