Optimal Pole Assignment for Discrete Linear Regulator With Deterministic Disturbances

Abstract

This paper presents the solution of the linear discrete optimal control to achieve poles assigned in a circular region and, meanwhile, accommodate deterministic disturbances. It is shown that by suitable manipulations, the problem can be reduced to a standard discrete quadratic regulator problem that simultaneously ensures: 1) closed-loop-poles all inside a circle centered at (β, 0) with a radius α, where | β| + α ≤ 1, 2) minimizes the cost functional, and 3) accommodates external input disturbance.
