Abstract

In this paper we apply recent results in multivariable robust control synthesis for linear parametervarying (LPV) systems to the control of a turbofan engine over a wide range of power codes. Seven linear, time-invariant (LTI) models are used in the control design. This results in an LPV controller consisting of seven LTI controllers, gain-scheduled via linear interpolation. A 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 point designs is compared with that of the LPV controller via closedloop step responses, under both constant and parameter-varying conditions.
