  • Abstract
    A theoretical approach is presented to digitally manipulating the drive frequency of an ac induction motor so as to allow the motor to be used in a closed loop positioning servo. Additionally, the basic power source can be a simple dc power supply such as a battery pack. A hardware demonstration of the loop is discussed which has achieved a convergence accuracy of a 0.3 mrad to a step input.
