The general theory introduced by the first three authors [IEEE Trans. Autom. Control AC-32, 583-592 (1987)] is used to develop a procedure for detection and diagnosis of changes in the poles of a multivariable linear rational system with possibly time-varying zeros. The procedure, which is based on an instrumental variable test statistics, is used to solve a vibration monitoring problem. This type of problem is described in detail and numerical results obtained from artificially generated as well as real-life data are presented to illustrate the excellent performance that can be achieved.
