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 ...

Robots positioning control revisited
Journal of Intelligent and Robotic Systems, 1990Positioning control systems for robot arms are presented within a general framework in view of unification and classification. Treating coupling torques from other links as an external disturbance reduces the design of the control system to that of SISO servomechanisms driving each of the robot axes individually.

ON THE POSITIVE REALIZATION OF CONTROLLABLE BEHAVIORS
IFAC Proceedings Volumes, 2002Abstract Positive linear systems, traditionally investigated within the state-space framework, have been recently analyzed within the behavioral setting, by focusing the attention on the autonomous case. Also, the positive realization problem has been fully explored in the special case of autonomous behaviors.

Curvature in force/position control
Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002If a rigid body is subject to a set of holonomic constraints then the set of allowed positions and orientations comprise a subspace in the group of rigid body motions. Consideration of the geometry of these constraint subspaces leads us to consider their second fundamental form. This allows us to predict the constraint forces and torques generated by a
