Preview Feedforward Compensation: LMI Synthesis and Flight Simulation

Yoshiro Hamada

Abstract

This paper proposes a novel synthesis technique for discrete-time preview feedforward compensation via linear matrix inequality (LMI). While an LMI synthesis condition for preview control in the previous research yields both feedback gain and preview feedforward compensation simultaneously, the proposed approach can derive feedforward compensation solely after feedback gain is designed in some way. LMI synthesis conditions for preview feedforward compensation are obtained based on H 2 , H ∞ and IP (impulse-to-peak) performance indices. Simulation results of disturbance attenuation using a research aircraft model are provided to show effectiveness of the proposed synthesis.
