Abstract : The main problem with using the modified bang-bang controller is the moderate amounts of feedback noise can lead to high levels of torque noise. This stems from a velocity squared term in the controller. This report presents computer simulation results from a study aimed at decreasing torque noise. Two approaches are (1) decrease feedback noise directly, and (2) modify the controller so that it is less sensitive to feedback noise. We recommend that the control designer decrease feedback noise as much as practical and then decrease controller gains as a function of velocity until acceptable levels of torque noise are achieved....
