In the present work the technique used is based on multirate -output controllers having a multirate sampling mechanism with different sampling period in each measured output quantity of the system. It relies mainly, under appropriate conditions, on the reduction of the original H ∞- disturbance attenuation problem to an associated discrete H ∞- control problem for which a fictitious static state feedback controller is to be designed, even though some state variables may not be available (measurable) for feedback purposes. The discrete linear open-loop system model under consideration (which includes a disturbance term) is systematically derived from the associated continuous 3th -order MIMO linearized open-loop model of a practical power system, with turbogenerator supplying power to an infinite grid through a step-up transformer and an appropriate transmission line.
