Recent results in multivariable robust control synthesis for linear parameter-varying (LPV) systems are applied to the control of a turbofan engine over its entire range of operation. Ten linear, timeinvariant (LTI) models are used in the control design. An LPV model of the turbofan engine is constructed and used to design an LPV controller. An Hoo model matching approach is employed such that the resulting closed loop resembles a decoupled set of second-order systems with specified rise time and overshoot. The performance of linear, Tioo point designs are compared with the LPV controller under both constant and parametervarying conditions. The LPV controller achieves excellent tracking of the desired values across large variations in power code.
