Feedforward compensation control of X-Y precise positioning table using inversed-sensitive function
precise positioning table driven by a Voice Coil Motor(VCM) will lead to a poor position precision
a feedforward compensation method based on inversed-sensitive function was proposed. Firstly
the system model was set up based on frequency domain identification
and the relationship between system disturbances and steady state error was established using final-value theorem. Then
an inversed-sensitive function was designed to compensate the effect of the disturbances on the stable error and to improve the positioning accuracy of the system. Finally
the experiments of different strokes were implemented on the
X-Y
table driven directly by the VCM to validate the efficacy of the proposed method. The experimental results show that the static errors of the system decrease from 2 μm to 0.2 μm with a micro positioning of 10 μm and a maximum acceleration of 6 mm/s
2
and those decrease from 2 μm to 0.4 μm with a macro positioning of 10 mm and a maximum acceleration of 6 m/s
2
. Obtained achievements verify the validity of the proposed method and provide a references for the subsequent study in high accuracy positioning servo system design.
