Stabilization of multirate sampled-data linear systems

Abstract This paper considers the design of multiple-input multiple-output digital control systems characterized by a non-standard sampling mechanism. It is assumed that the various outputs of the plant are measured at different rates, which can be definitively less than the unique rate adopted for the inputs updating, or else at different times. A pole-placement problem is solved by resorting to a controller composed by a periodic state observer and a non-dynamic control law.
