This thesis aimed to eliminate tracking
error of traveling a circular profile on the CNC machine tools. Friction is one of the
most significant source of nonlinear disturbance for the motion control which caused
by the relative motion of different contact surface at the low velocity. The nonlinear
component of friction such as static friction (stiction) and the Coulomb friction should
be overcome so that the tracking error will be eliminated. When the X-Y tables are
tracking a circular profile, quadrant glitches appear at ninety degrees intervals, i.e. the
motion of one axis has a zero velocity crossing and reverses direction.-This thesis is aimed to eliminate tracking
