A Framework for Variational Grid Generation: Conditioning the Jacobian Matrix with Matrix Norms

SIAM Journal of Scientific Computing, 2000
The authors introduce a new framework for the construction of functionals which characterize properties of candidate mappings. The optimal mapping is obtained by solving most commonly numerically the Euler-Lagrange equations corresponding to the variational problems of minimizing global functionals. Numerical experiments are performed for illustration.

A parallel algorithm for the Jacobian matrix of a manipulator

Microprocessing and Microprogramming, 1993
Abstract We present a parallel algorithm to compute the Jacobian matrix of a N links manipulator in a shared memory SIMD system of processors. It is based on a new parallel algorithm to prefix computation that we will apply to solve the linear recurrence equations of the Jacobian matrix.

On updating the inverse of the Jacobian matrix

Computers & Chemistry, 1978
Abstract An algorithm is given for updating the inverse of a matrix which has changed by only a few elements. This algorithm has been found to reduce the computing time required to calculate the inverse of the Jacobian matrix during the solution of ordinary differential equations.

Approximate Jacobian robot control with adaptive Jacobian matrix

42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004
In this paper, we present approximate Jacobian feedback control laws for setpoint control of robot with uncertain kinematics from joint space to task space. An adaptive law is proposed to update the approximate Jacobian matrix to improve the performance.

The Generalized Jacobian Matrix and the Manipulators Kinetostatic Properties

ASME 2010 10th Biennial Conference on Engineering Systems Design and Analysis, Volume 3, 2010
Manipulator kinetostatic performances are usually investigated considering only the geometrical structure of the robot, neglecting the effect of the drive system. In some circumstances this approach may leads to errors and mistakes. This may happen if the actuators are not identical to each other or when the employed transmission ratio are not ...
