Block-decomposition of a Linear Discrete Large-scale systems Via the Matrix Sign Function

행렬부호 함수에 의한 선형 이산치 대단위 계토의 블럭-분해

An algorithm for block-decomposition of a linear, time-invariant, discrete large-scale systems is presented, based upon the matrix sign function on Z-plane. The block-decomposition is performed by defining a reference circle, a circular stripe and projection operators. Simulation study shows that the presented algorithm is very useful for multivariable control system's analysis and design.
