Abstract :
Principal component analysis is used to reduce a sixteenth-order linear dynamical model of a turbofan jet engine to a robust fourth-order model. An optimal controller based on a quadratic performance criterion is presented for the reduced model. The quadratic weights are determined so as to obtain suitable time-domain responses for an approximate system consisting of low-order decoupled subsystems. Owing to the small number of gain coefficients, the controller is comparatively easy to tune. The robot optimal controller was verified by digital simulation. Simulation results are presented.<>
