摘要: In this paper, by applying a group of specific orthogonal wavelet packet to Eykhoff algorithm, a new impulse response identification algorithm based on varying scale orthogonal WPT is provided. In comparison to Eykhoff algorithm, the new algorithm has better practicability and wider application range. Simulation results show that the proposed impulse response identification algorithm can be applied to both deterministic and random systems, and is of higher identification precision, stronger anti-noise interference ability and better system dynamic tracking property.
