Hierarchical least squares based iterative algorithms for two-input single-output Hammerstein finite impulse response systems

This paper focuses on the identification problem for finite impulse response systems through using the hierarchical identification principle. Based on the hierarchical identification principle, the hierarchical based least squares iterative algorithm is proposed to estimate the parameters of the two-input single-output Hammerstein finite impulse response systems. Finally, a simulation example is given to test the effectiveness of the proposed algorithm.
