Strictly proper projective controllers for disturbance attenuation

Abstract

A design methodology is presented which applies projective controls to the disturbance attenuation problem for large flexible structures. Through this method, low-order strictly proper controllers are designed which improve the disturbance attenuation properties of the system. A new parameterization of the closed-loop system in terms of free parameters in the projective controller leads to an auxiliary minimization problem which determines the parameters of the controller. A flexible structure example demonstrates the use of this methodology.
