The Design of Fuzzy Slide-mode Controller for Machine Tool Axis with Nonlinearity

Aiming at the nonlinearity of machine tool axis, this paper presents the methodology of fuzzy slide-mode controller based on slide-mode control theory in the viewpoint of VSS. As the result of independence on the exact model of controlled plant, the slide-mode controller is suitable for solving nonlinear problems, and can guarantee the stability of controller. The results of simulation on backlash verify the effect iveness of this methodology.
