abstract

The requirement for gas turbine engines to operate over wider ranges has resulted in today’s more sophisticated engines with multiple controls. Current control philosophy for such powerplants is to adopt separate control systems for each of the major components with the minimum of communication between them. Interactions between the various control parameters can, however, seriously degrade the performance, and a design strategy aimed to take account of these interactions — the multivariable approach — may be better. Although several multivariable design methods have been proposed, most are highly theoretical and a need exists for a more practical straightforward procedure. This paper aims to demonstrate such a procedure, based on the characteristic locus technique, for the design of a gas turbine multivariable controller.
