If is an upper Hessenberg matrix, regular and irreducible, we propose two methods to calculate the inverse of A. The first is based on QR factorisation, the second on Y. Ikebe's method. We compare the numerical results using a microcomputer. DOI: 10.1016/0965-9978(93)90008-H 年份: 1993...
(TPS), maps the problem in Euclidean space to TPS, is utilized for inverse solving of 1–8 DOFs of the upper limb, and provides a mathematical description of upper-limb motions. The results largely satisfied realistic motion of the upper limbs. The coordinate information of a maximum of six...

We will need the following classical bounds for the norm of the inverse matrices which is due to Richter [25] (see also [18] for a different proof). Recall that for a matrix A, \(\Vert A\Vert \) stands for the operator norm \(\ell ^2\rightarrow \ell ^2.\) Theorem...
Here,τcdenotes the torque applied to the robot joints. The termsB(q)andn(q,q˙)account for inertial properties and dynamic effects including Coriolis and gravitational forces.JA†(q)is the pseudo-inverse matrix of the analytical Jacobian. Additionally,x~randx~tindicate the radial and tangent...
