SINOPSIS

A multivariate discrete control system that has the property of functioning in two time scales and is characterized by uncertainty of the ratio of speeds of fast and slow motions is considered. A new approach to the decomposition of the initial model of a multivariable object into slow and fast acting subsystems is developed; this approach makes it possible to synthesize a composite regulator that is invariant to the change of the ratio of speeds of fast and slow variables of the system. The results of studying sensitivity of thus separated closed-loop control system to the change of the ratio of speeds of fast and slow motions under single-rate and multirate sampling are presented.
