Approximate realization based upon an alternative to the Hankel matrix: the Page matrix

Systems and Control Letters, 1982
The Ho-Kalman algorithm creates a minimum realization of a system, when given a series of deterministic Markov parameters. However, when such a 'truncated' series of Markov parameters has been disturbed with noise, an approximating Hankel matrix has to be constructed for applying the realization algorithm.

Hankel matrix transformation of the Walsh–Fourier series

Applied Mathematics and Computation, 2013
The Hankel matrix has various applications. In this paper we prove that Hankel matrix is strongly regular and apply to obtain the necessary and sufficient conditions to sum the Walsh-Fourier series of a function of bounded variation.

Testing the rank of the Hankel covariance matrix: a statistical approach

IEEE Transactions on Automatic Control, 2001
Summary: The rank of a Hankel matrix, corresponding to a system transfer function, is equal to the order of its minimal state space realization. The computation of the rank of a Hankel matrix is complicated by the fact that its block elements are rarely given exactly but are estimated instead. In this note, we propose new statistical tests to determine
