Air torque position damper hysteresis

Flow Measurement and Instrumentation, 2020
Abstract The purpose of this paper is to determine the effect of the air torque position (ATP) damper hysteresis on the accuracy of air velocity measurements and the adequacy of the ATP damper mathematical model tested in the present study. A total of three dampers with non-cascading blades were examined: a damper with a single flat blade, a damper ...

Effect of hip position on gravity effect torque

Medicine & Science in Sports & Exercise, 1994
Hip position has been hypothesized to influence gravity effect torque (GET) at the knee during isokinetic testing; however, no data exist to support or refute this hypothesis. Therefore, the purposes of this study were 1) to determine if a significant difference exists between GET in seated and supine positions, 2) to determine the effect of the supine

POSITION/TORQUE CONTROL OF A SPACE ROBOTICS ARM

IFAC Proceedings Volumes, 2006
Abstract Torque sensors are used in space robot joints to increase robot capabilities and operational flexibility. Cascaded to a load position loop, a torque loop increases the performance of a position servo facing large variations of load inertia, typical of space robot arms.

Influence of Position on Knee Flexor Peak Torque

Journal of Orthopaedic & Sports Physical Therapy, 1988
The purpose of this study was to determine the influence of position on knee flexor peak torque production. Gravity effect torque and knee flexor peak torque were measured in both supine and prone positions for 20 male and female volunteers between the ages of 22 and 35 years with no history of left lower extremity pathology.

Torque-position transformer for task control of position controlled robots

2008 IEEE International Conference on Robotics and Automation, 2008
Joint position control is a dominant paradigm in industrial robots. While it has been successful in various industrial tasks, joint position control is severely limited in performing advanced robotic tasks, especially in unstructured dynamic environments.

Position sensorless BDCM control with repetitive position-dependent load torque

2010 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2010
This paper addresses the position sensorless control for brushless DC motor (BDCM) with repetitive position-dependent load torque which is a function of the absolute rotor position (not incremental rotor position). The robust sensorless control is composed of sensorless control and robust speed control.

Air torque position damper energy consumption analysis

Energy and Buildings, 2015
Abstract The damper used for the control of airflow in heating, ventilation and air conditioning systems can constructively be adapted to measure the air velocity with its moment characteristic. It is a device that indirectly determines the air velocity by measuring the position of the blades and the air stream moment acting on it.

TCP position tolerances in joint torque minimizations

Proceedings. 1998 IEEE/RSJ International Conference on Intelligent Robots and Systems. Innovations in Theory, Practice and Applications (Cat. No.98CH36190), 2002
A new algorithm for link and path optimizations of manipulator arms is formulated. The algorithm considers precision in tool center point (TCP) positioning. A penalizing function is introduced to allow divergence from the desired TCP locations. The ever increasing operational demands of robots presuppose high power drives which tends to adversely ...
