Abstract

According to a class of longitudinal model of missile, an output feedback controller design methodology of LFT-LPV system based on full block scaling matrix is proposed which reduce the conservatism effectively. Firstly, the system nonlinear model is transformed into a LFT-LPV form by data fitting in the interested working region. Then, using S-Procdure, full block scaling matrix with a specific configuration is chosen to satisfy the inequality, avoid solving a infinite numbers of LMIs on the trajectory of all possible varying parameters, and then give the method of the output feedback controller design which can satisfy the given performance target based on LFT-LPV system. Finally, the digital simulation results prove the availability of the proposed method.

Key words： linear parameter system; linear fractional transformation; full block scaling matrix; output feedback; LMI
