摘要：

This paper addresses the design of a feedforward controller that enables machine tool axes to have the desired dynamics. The controller adopts a simple configuration of a reference model and compensators for feedback and mechanical dynamics. It improves the dynamic response of conventional cascaded control based on performance requirement. The designed feedforward controller is implemented for the contouring control of a high-speed and high-accuracy machining center. It is shown that the contouring accuracy in submicron-level has been achieved by using the designed controller. (C) 2011 CIRP.
