| Summary: | 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 1�m is achieved. Contouring error of
less than 1���m is achieved as well.
