Accuracy is one of the important factors in manufacturing. This study aims at improving positioning performance for existing actuator holds time lag and low dynamics. The control method to propose consists of lower order model identification and model referenced predictive anti phase pitch driving control based on the model output. In first process, displacement is extrapolated from calculation the time lag from vibration observation point using online N4SID model corresponded non-linear. Next, equipment is added pulse acceleration with pitch driving to anti phase direction of displacement and control vibration. This method was applied to machine. The result, shows that residual vibration for a short time and vibration displacement is suppressed to 22% at the time of the usual PI control and to 12% at un-controlling, respectively. This study reports the reduction of control elapsed time using switching control in each neighbor of maximal amplitudes.
