In this paper we show that the MOESP (Multivariable Output-Error State sPace) class of subspace model identification (SMI) schemes can be extended to identify Wiener systems, a series connection of a linear dynamic system followed by a static nonlinearity. Methods are developed for two cases: firstly when the nonlinearity is not an even function, and secondly for systems which include even nonlinearities. Simulations are used to demonstrate the efficacy of these algorithms, and to compare them to existing, correlation based techniques.
