碩士 === 國立中興大學 === 機械工程研究所 === 82 === This thesis presents the design of a F-100 turbofan engine controller using Multivariable Frequency-Domain Method proposed by Edmunds. The idea of this method is to design a controller which has simple structure. The parameters of the controller are adjusted so that the closed-loop frequency response is as closed as possible, in a least square sense, to a desire response. In this thesis, an operating point(sea lever, static, PLA=52) is selected as a design point, and a controller is designed at this point. First, a linear state-space model obtained from a nonlinear engine model is transformed into transfer function and a scaling matrix is selected. Next, Edmunds algorithim is used to design a controller. Finally, the performance of the controller is evaluated by computer simulation and the performance of different controllers are compared.
