Adaptation from PI output to PWM???

    hi everybody!
    i am implementing a control loop of speed for a DC motor. The motor is
    controller throught PWM signal and the feedback is obtained with an
    optical encoder. Has anybody solved a similar system?
    Anyway, when the PI controller generates the signal from the speed
    error which is the way to pass this signal to the PWM? I mean, does
    somebody know which is the transformation between this signal and the
    compare value input to the PWM generator?
    Thanks in advance
