Abstract: The use of compound actuators in both magnetic and optical disk files has become a means of achieving increased servo actuator bandwidths. A compound actuator, comprised of a fine actuator ...

Abstract: This paper presents the precision control of drive devices with significant stick-slip friction. The controller design follows the Pseudo-Derivative Feedback (PDF) control algorithm. Using the ...

Abstract: This paper addresses the servo design for a real-time, laser-tracking, three-dimensional (3-D), position measurement system. The 3-D measurement system uses two sets of tracking mirrors to shine ...

Abstract: In this study, we present a new compensator design for systems with position dependent friction. Position dependent friction occurs between revolving parts that are conventionally used in mechanical ...
