To compensate effectively such elements as the nonlinearity,uncertainty and unmodeled dynamics in electro-hydraulic servo system,a mathematic model of the system was turned into an equivalent linear model including an item of identification error which called 2nd uncertainty of adaptive dynamic recurrent fuzzy neural networks(ADRFNN).

By utilizing the characteristic that amplitude correlation between neighbor bins of the same signal is better than different signals, an improved method based on the amplitude correlation between neighbor bins to eliminate the permutation indetermination was proposed.
