... tools MIMO systems motion control variable structure systems Contouring errors, defined as the normal deviation from the desired reference tool-path, occur in multi-axis motion control systems due to tracking errors of individual servo drives. In Part I of the paper, two types of contour...

...Haojiong Zhang; Robert G. Landers A general precision motion control methodology for complex contours is proposed in this paper. Each motion servomechanism dynamic model is divided into a linear portion and a portion containing nonlinear friction, unmodeled dynamics, and unknown disturbances...

This paper focuses on the motion control and experiment validation. First, the inverse kinematics is presented, which gives the relationship between the ram travel and (i...
