Abstract Model and Controller Design for an Unstable Aircraft. (Reannouncementwith New Availability Information)

摘要

In this paper, we consider an unstable system with a time delay as an abstractmodel of an aircraft longitudinal motion for the short period. In our controller design we want both sensitivity reduction and robustness to certain unmodelled dynamics. Using standard arguments, these control objectives are formulated as an H infinity optimal control problem. We show in detail how to compute the optimal controller for this distributed model. A numerical example is given to illustrate the computational procedure.... Robust control, Delay systems, H infinity, Interpolation theory.
