Application of AVR Single-slice Process in Direct-servo-actuated Control System

This paper introduces th e closed loop direct-servo -actuated control system which is realized by a n ew type AT90S8515microcontroller.The specialty of AVR sing le -slice p rocess and the setting of relative reg ister of PWM reg ulating speed in AVR microcontroller were particularly introduced.The hardware circuit and software desig ned were g iven,the measure method of position and velocity was descri bed.It was shown by experiment that the use of the AVR sing le-slice pro cess can improves the actual effect of the desig ned system and the interfac e hardware is simplified g reatly and the ability of resistance disturbance is improved.It has acquired a g ood control result in practices.
