Time-Varying Optimum Synchronous Control for Multiple-Axis Systems

Abstract

This paper presents a synchronous control method for multiple-axis systems such as synchronization and cooperation of all axes. The proposed control system is constructed in terms of time-varying controller obtained for the time-varying performance index, in which the position synchronization can be realized for the circular path and/or the straight line path. The proposed control method is applied to the X-Y table which is a two-axis system. In the experiments, the proposed control method improves the precision of the path and reduces the fluctuation of the path by disturbance, in comparison with the conventional independent control for each axis.
