Abstract: | The polynomial matrix using the block coefficient matrix representation auto-regressive moving average (referred to as the
PM-ARMA) model is constructed in this paper for actively controlled multi-degree-of-freedom (MDOF) structures with time-delay
through equivalently transforming the preliminary state space realization into the new state space realization. The PM-ARMA
model is a more general formulation with respect to the polynomial using the coefficient representation auto-regressive moving
average (ARMA) model due to its capability to cope with actively controlled structures with any given structural degrees of
freedom and any chosen number of sensors and actuators. (The sensors and actuators are required to maintain the identical
number.) under any dimensional stationary stochastic excitation.
