Adaptive PI control method for positioning control using linear slider feedforward control approach

In this paper, we present a feedforward control system using adaptive PI strategy for a positioning mechanism with stand. Due to the rapid motion of a moving table, the vibration phenomena in a stand may be induced by the reaction force of a motion of a moving table. However in previous research, the dynamics of the stand does not consider. Besides, in such a system, rapid and accurate positioning of a moving table is required for the high productivity and quality. To cope with this problem, we present the dynamic model of the positioning mechanism with stand using linear slider, apply a feedforward control method with adaptive PI control strategy to the system and show the effectiveness of our method, compared to the conventional research.
