Abstract

This paper treats the output feedback H2 control with regional pole placement condition (the mixed H2/D-stability control). In general, this problem is a BMI problem which is difficult to be solved theoretically. The purpose of this paper is to propose an iterative method for obtaining a sub-optimal solution of the mixed H2/D-stability control problem. The key idea of this paper is to employ a full-order observer-based controller. The proposed method produces a sequence of controllers which approaches the unconstrained globally optimal H2 controller while it satisfies the D-stability constraint. A numerical example shows the effectiveness of our method.
