H/sub /spl infin// identification for nonlinear system based on generalized frequency response function
Proceedings of the 4th World Congress on Intelligent Control and Automation (Cat. No.02EX527) - Tập 1 - Trang 114-118 vol.1 - 2002
Tóm tắt
Based on the GFRF (generalized frequency response function), H/sub /spl infin// identification for nonlinear system is investigated using the set membership identification theory. We applied the three-order truncated Volterra series to describe the nonlinear system, and accomplished the model identification by the Householder transformation that is a kind of orthogonal decomposition, and then derived the GFRF of the system. Moreover, by means of the set membership identification we give a measure of the model perturbation in a form well suited for H/sub /spl infin//-control methodologies. The effectiveness of the proposed procedure is tested on the numerical simulation.
