Digital Control of a DC Motor Using Pulse Width Modulation
Ephraim Pobe & Mark McDermott
Advisors: Dr. R. Jetton & Dr. I. Ahn

A control system design, using a microcontroller generated pulse width modulation to control the velocity of a motor, will be described in the following presentation. Control systems like this are the basis for robotic control, automation, and other industrial engineering topics. The DC motor used was an Electro-Craft model m-1030 with a maximum power of 130 watts and a maximum current of 60 amps. A moving coil tachometer was used which was mounted on the rear end of the shaft of the motor to measure the velocity of the shaft. The advanced 8 bit microcontroller unit of the 68HC11 family is used in this design. It delivers a control signal to power amplifiers which drive the motor and specifies the rotational direction of the shaft.
