Reduced form of the interactor matrix
J.F. Lafay, P. Zagalak, Haydeé Herrera · IEEE Transactions on Automatic Control · 1992
Some structural results about the interactor of a given right invertible system are presented. An original form for this operator, which directly exhibits structural information such as infinite-zero structure or essential orders, is provided. Moreover, this form allows the linkage of the infinite and essential structures of a system.>
