Improved Step-Motor Control

About

Summary ISU researchers have developed robot and stepper motor control software that contributes to the improved operation of robots Development Stage This technology has been applied to a flexible robot arm that moves a large distance in the range of 90 to 180 degrees using a minimal amount of time Description The Bouton-McConnell Stepper Motor Controller for Vibration-Free Fast Response, involves control techniques that permit stepper motors to behave like closed loop DC motors when implemented using  Robust Vibration Suppression (RVS) control techniques. This control technique enhances noise suppression and can achieve high speeds without sacrificing the control of residual vibrations. It can be applied to currently operating stepper motor systems. Advantage Robust (minimally affected by system operating dynamics) Fast (robot response time is minimized) Quiet (permits broad band noise suppression) Versatile (can be applied to a variety of control systems) Application Robotic controls; stepper motor control Patent Information Country           Serial No.        Patent No.       Issued Date United States  08/912,283      6,002,232*       12/14/1999 United States  09/303,462      6,011,373*       1/4/2000 Direct Link http://isurftech.technologypublisher.com/technology/19306 Category(s) Engineering & Physical Sciences Research Tools & Design Tools Sensors & Controls Software & Information Technology ISURF #1832
