Abstract

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 the previous researches, the dynamics of the stand does not consider. To cope with this problem, we present the dynamic model of the positioning mechanism with stand using linear motor and apply a feedforward control method with adaptive PT control strategy to the system. Experimental results demonstrate the effectiveness of our method, compared to the conventional research. Especially, the efficiency of an adaptive PI control strategy to the actual system is shown.
