Abstract :
An approach for improving the contouring performance of a computer controlled x-y table by using a neural network to interpolate between measured optimal cross-coupling gain values has been developed. The paper discusses the implementation of the proposed control structure for circular and other curved trajectories. Experimental results show that for a circular trajectory contour error is reduced as compared to the conventional uncoupled control of the two axes
