Abstract: Aiming at the problems that actual objects are changeful and traditional predictive functional control can only fit limited points in the time domain of prediction,being unable to optimize the target function in the whole time domain of prediction,a predictive functional control method based on wavelet function and Hammerstein model is proposed.The inner model parameters are adjusted automatically depending on repeated identifications.The wavelet properties of compact support and multi-scale analysis can ensure the target function of the whole time domain optimization,some important points fitting and the optimal parameters aggregation.The theoretical analysis and simulation show the approach has better rapidity and the ability of model's anti-mismatch.
