Abstract
A computationally inexpensive and stable method for real-time identification of nonlinear objects of the Urysohn type conducted by applying a model improvement steps for every set of recorded instantaneous input and output values.
Claims2
A method for identification discrete Urysohn models with multiple inputs taking integer values, comprising the steps of:
- (a) providing a recorded output value and sequences of integer input values,
- (b) use said integer input values along with time indices as positions of elements of a multidimensional matrix, representing said Urysohn model, for
- (c) computing a difference between said recorded output value and a sum of all said involved matrix elements and
- (d) correcting all said involved matrix elements by adding to each of them a value that reduces said difference between said recorded output value and said sum of involved elements and
- (e) repeating steps (b) through (d) for a plurality of available data, that are sequences of said input and said output values until said computed difference (c) falls into expected range.
