Identification of a MIMO continuous-time transfer function model with different denominators

This paper is about the identification of a MIMO continuous-time (CT) transfer function model with different denominators. A new algorithm is proposed with two main steps. The first step consists of the estimation of an overparameterized MIMO CT reinitialized partial moment model and the second one performs a moment-based transfer function model reduction. For the unknown structure case, a system structure estimation procedure is given.
