Abstract

An adaptive recursive subspace identification algorithm in complex domain was proposed for recursive estimation of state space model of linear time-varying systems. The unbiased Hankel matrices were updating with variable forgetting factor. Then recursive estimation algorithm of extended observation matrix was realized with the help of orthogonal PAST algorithms. Finally, the adaptive updating form of variable forgetting factor was designed with eigenvalues' Euclidean-distance information of industrial system parameter matrices. Two simulation results show tracking performance of new algorithm is faster and better than traditional one.

Key words： recursive subspace identification algorithm; complex domain; variable forgetting factor; Euclidean-distance
