A method of calculating recovery commands for numerical controlled system that an upper controller provides position commands to a servo driver to drive a motor. A memory space is provided to store the position commands, and then a position matrix and a transformation matrix are read. Finally, the transformation matrix is multiplied by the position matrix to calculate the coefficients of a position polynomial and a plurality of position interpolations. In addition, a velocity polynomial and an acceleration polynomial can be calculated. Therefore, the position commands are calculated to recovery as a high-order differentiable continuous polynomial to synchronize the servo driver and the upper controller. |
