    Angry Regulated power supply problem

    Hello PIC guys! I made PIC controlled power supply for engraving head control(12VDC motor). I used HPWM command for output. I wrote code for basic PWM control , ADC reads value from potentiometer and change duty of HPWM command , but I don’t know how to write feedback procedure which can allow control output voltage regardless of current.
    Please help me, any ideas welcome, maybe I made mistake in my circuit design that's why I provided a diagram
    Vladimir.
