Time-delay Estimation for MIMO Delay Systems with Unknown Structures

doi:10.16182/j.issn1004731x.joss.20-0034

Abstract

Abstract: In the unknown-structure delay system modeling, time-delays lead to a mismatch between the system inputs and outputs on the timeline and cause low system modeling accuracy. A time-delay estimation method is proposed for the unknown-structure MIMO (Multiple-Input Multiple-Output) delay systems. A general mathematical description is given from the algebraic point of view, the delay correlation function is defined, and a quantitative constraint between system input-output and time-delay is constructed. A greedy time-delay search algorithm is introduced based on the delay correlation function. Simulation experiments and real data experiments show the availability of the proposed method.

Key words: time-delay, delay matrix, delay system, delay correlation function, greedy search algorithm
