“…Highly coupled 6-DOF multi-axis motion has often been assumed to be six independent decoupled motions [1,2,[45][46][47][48]. Since this is a significant factor that contributes to modeling error, the Newton-Euler Equation (9) (which introduces coupling between axes) is proposed.…”

A nonlinear passive observer (NPO) for estimating the time-varying velocity vector of a multi-axis high-precision motion control stage is presented. The proposed nonlinear estimation strategy is developed based on a Lyapunov stability analysis, which proves that the NPO is stable. Three test cases are used to investigate the performance of the proposed observer. Experimental results are given to demonstrate the performance of the proposed NPO in accurately estimating time-varying velocity during alignment, reciprocating motion, and multi-axis motion in high-precision motion control applications.

“…These devices eliminate the strain, backlash, and hysteresis that limited the precision of position control and by being contactless devices, long lifetime and fatigue problems are minimized. Several prototypes have been proposed with strokes of tens of mm and resolution in the nanometer scale in one or more DoF [18][19][20][21][22][23]. In comparison with the piezoelectric positioners, the active magnetic levitation systems can offer similar accuracies for longer motion ranges.…”
