- Abstract
- A bilinear Schwarz approximation method has been proposed in the literature for reducing the order of discrete-time systems. The reduced model derived by the method preserves the stability and first few time-moments of the original one. This paper shows that the method can be modified so that the impulse response energy of the original model is also conserved in the, reduced model without destroying the stability and time-moments preserving properties.
