Mathematics and Computers in Simulation (MATCOM), 1985, vol. 27, issue 5, 479-484

Abstract: This paper discusses the application of Walsh functions expansion to reduce the order of a linear time-invariant system. First, Model reduction of linear continuous systems by matching the Walsh spectra of output responses of the original and reduced models, subject to the specific inputs, is discussed. Secondly, model reduction under linear constraints on the structure of the reduced model is discussed. The latter has the advantage that the reduced model is stable and/or cause no steady-state error.
