Dyadic Expansion Method and Its Application to the Design of Boilerturbine Unit Load Feedback Control System in a Power Plant

In this paper the dyadic expansion method—a multivariable frequency-domain method and its practical form (dyadic approximation method) is described briefly.It is applied to design Boiler-Turbine Unit Load Feedback Control system (BTULFCS).A Simple and convenient engineering method about selection of ω₁ of the design method is proposed in this paper.Finally,comparing with two other major multivariable frequency domain methods we conclude this method is more suitable to design BTULFCS.
