Torque-position transformer for task control of position controlled robots
2008 IEEE International Conference on Robotics and Automation, 2008Joint 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.

Positive controllability of positive dynamical systems
Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002The paper is devoted to a study of constrained controllability and controllability for linear dynamical systems if the controls are taken to be nonnegative. In analogy to the usual definition of controllability it is possible to introduce the concept of positive controllability. We concentrate on approximate positive controllability for linear infinite-

A BRUSHLESS SYSTEM FOR POSITION CONTROL
IFAC Proceedings Volumes, 1983Abstract The problems related to the use of a Brushless motor in a position control are analysed. The motor is a P.M. Synchronous motor, for which a magnetically isotropic or anisotropic structure may occur, according to the magnets arrangement in the rotor.The attention is firstly devoted to the drive system prerogatives, which must be suitable for ...

Learning force control with position controlled robots
Proceedings of IEEE International Conference on Robotics and Automation, 2002The paper applies a previously presented method for accurate tracking of paths to force control. This approach is very simple since it does not require a joint torque/motor current interface but only a positional interface. It can be applied with elastic end-effectors (sensors) as well as with stiff environments where most elasticity is in the robot ...

Microcomputer position control system
Microprocessors and Microsystems, 1979Abstract Minimization of the travelling period when a digital motor is used as a positioning actuator is discussed. Two aspects are involved: the exploitation of motor acceleration capability by using a microcomputer as a programmable controller and the development of support subroutines to deal with the interaction between the required position and ...

A hybrid position/force control for robot manipulators with position controllers
Proceedings IECON '91: 1991 International Conference on Industrial Electronics, Control and Instrumentation, 2002A new hybrid position/force control scheme over a position control scheme is proposed. The control scheme modifies the position command for force control against the constraint surface of the environment and is very easily designed and implemented. The merits of the control scheme are that it can cope with a change of constraint conditions and a small ...
