This paper presents a generalization of the chain-scattering representation
to the case of general plants. Through the notion of input-output consiste
ncy, the conditions under which the generalized chain-scattering representa
tion (GCSR) and the dual-generalized chain-scattering representation (DGCSR
) exist are proposed. The generalized chain-scattering matrices are formula
ted into a general parameterized form by using the generalized inverse of m
atrices, Some algebraic system properties, such as the cascade structure pr
operty, the symmetry (duality) of the GCSR's and DGCSR's, are studied.
