Abstract :
In this paper, design and implementation of an intelligent disturbance weighting function for H-based precision positioning control system is presented for an AC motor drive X-Y table positioning mechanism. The system works with a robust feedback controlled, enhanced by an outer loop integral control. The objective is to achieve high tracking and contouring performances even in the presence of uncertainties and disturbances. The effect of crosstalk between the two axes is considered as disturbance that is treated by intelligent estimated disturbance weighting functions using adaptive neuro fuzzy inference system (ANFIS). The developed controller is implemented experimentally, and a tracking performance of less than 1μm is achieved. Contouring error of less than 1μm is achieved as well.
