TY - JOUR ID - 71043 TI - Further Observations on Blocking Zeros in Linear Muitivariabie systems (RESEARCH NOTE). JO - International Journal of Engineering JA - IJE LA - en SN - 1025-2495 AU - Lucas, C. AD - Intelligent Systems, Sharif University of Technology Y1 - 1991 PY - 1991 VL - 4 IS - 1 SP - 72 EP - 75 DO - N2 - While attempting to clarify the confusion concerning the conceptualization of "blocking zeros" in state space in the recent literature, some new observations are made on the relationship between pole-zero cancellation and transmission blocking. An important distinction between uncontrollable and unobservable eigenvalue s is pointed out; and it is argued that the description of a Blocking Zero, at the functional-behavioral level, is not sufficient.
