Discrete-time robust pole placement control with minimum auxiliary entropy and individual state variance constraint

摘要

In this paper, a robust pole assignment dynamic controller, which drives the discrete-time closed-loop system in order to satisfy the individual state variance constraints, is proposed for minimizing the auxiliary entropy function. Pole placement constraints can be achieved through individual state variance constraints and H{sub}∞ norm constraints. A robust dynamic output feedback controller will first be developed using an upper bound covariance control technique for linear perturbed discrete systems. This paper will also derive the necessary conditions for which the above robust dynamic output feedback controller can minimize the auxiliary entropy of the closed-loop transfer function.
