A cruise control system has been designed, tested, and built for use in the Sunseeker 99team's solar car. A proportional, integral, derivative (PID) controller is used to control motor speed. The desired speed is entered onto a keypad, with one decimal place for accuracy. This desired value is also displayed on output LEDs. The actual speed is calculated and compared to the desired speed. The PID controller uses this error to calculate the necessary change in output voltage to the motor controller. The Sunseeker 99 team is planning to use this cruise control with an Australian Csiro motor, but they have not yet purchased the motor. However, the system was found to function properly using a small test motor.
