In this paper, a method for identification of low-order output-error
models expressed in terms of Laguerre basis functions is presented. The
identification problem is formulated as a rank-constrained optimization
problem in the Laguerre domain, which can be solved efficiently using
nuclear norm regularization. Since the identified models are of low
order, a minimal state-space realization of the system can be obtained
without the use of additional approximative model-order reduction steps.
