Abstract : A study of various modal properties of linear, dynamical systems is carried out in this investigation. The problem of constructing minimum-state realizations of transfer function matrices is considered in detail. A solution to the problem of determining the minimum number of outputs required to observe all the dynamic modes of a system and the minimum number of inputs required to excite all system modes is presented. Algorithms for removing uncontrollable and unobservable state variables from time-variable as well as constant parameter systems are developed.
