Model-Reduction of Linear Discrete Large-Scale Systems

행렬부호함수를 이용한 이산치 계통의 모델 저차화

This paper presents an approach for determining the discrete reduced-order models for largescale system by using matrix sign function. We define projection operators based on the matrix sign function and develop the algorithm for model-reduction by using them. Simulation studies show that the proposed altgorithm is very useful.
