A hybrid position/force control for robot manipulators with position controllers

Proceedings IECON '91: 1991 International Conference on Industrial Electronics, Control and Instrumentation, 2002
A 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 ...

Stabilization with positive and quantized control

Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2003
Asymptotic stabilization for a class of nonlinear cascades in feedforward form is achieved with positive (negative) control. For the same class of systems practical stabilization is achieved by means of a quantized control scheme, i.e. with a control action that takes values only in a discrete set.

Positive Position Feedback (PPF) Control

2013
This chapter presents the design of a positive position feedback (PPF) controller based on low-pass filters and band-pass filters. In Sect. 6.1, the principle of the PPF controller is presented based on the single degree of freedom (SDOF) case. In Sect.

Position-based fluid control

Proceedings of the 19th Symposium on Interactive 3D Graphics and Games, 2015
We present a novel fluid control method that is capable of driving particle-based fluid simulation to match a rapidly changing target while keeping natural fluid-like motion. To achieve the desired behavior, we first generate control particles by sampling the target shape and then apply a non-linear constraint to each control particle, with its ...

Remotely Controlled Positioning Lasers

Medical Dosimetry, 1991
Positioning lasers used in radiotherapy generally require little adjustment. When required, this is easy to do for sidelights, but can be difficult and time consuming for ceiling mounted lasers. For this purpose, we have modified a commercial positioning laser by incorporating a device for rotating the alignment adjustment screws. This device is driven

The vibration controller design using positive position feedback control

2013 13th International Conference on Control, Automation and Systems (ICCAS 2013), 2013
We propose vibration controller design using positive position feedback (PPF) control. The five pairs of electromagnetic actuators and sensors are used to control strip vibration. Strip was modeled using finite element modeling (FEM). To reduce the order of the large scale model, the Krylov subspace technique was used.

ON THE POSITIVE REALIZATION OF CONTROLLABLE BEHAVIORS

IFAC Proceedings Volumes, 2002
Abstract 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), 2002
If 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

A position control system design

The 3rd IEEE International Workshop on System-on-Chip for Real-Time Applications, 2003. Proceedings., 2004
A Position Controller is a device used in many applications, such as controlling the movement of an elevator. In this paper, we examine the technological issues surrounding the development of an integrated circuit of a position control system. This system has been designed using Magic CAD software.
