...Hongbin Li; Nina Sun; Zhihao Wang Purpose This study aims to improve the positioning accuracy of a large-scale parallel pose alignment mechanism by calibration and error compensation. Design/methodology/approach The dynamic modelling of the parallel pose alignment mechanism is achieved using...

... that equation (2) represents a linear system, the derivative appears linearly, i.e. ∂S/∂a = 0, ∂S/∂b = 0, and ∂S/∂c = 0. The matrix equation for a, b and c is formulated as Different from the traditional error compensation algorithm, in this paper, a special error compensation strategy is proposed...
