Özet

In this paper, a new method is proposed to determine a set of robust stabilizing PI controllers
for a given single-input single-output linear time invariant (SISO LTI) system with multiplicative
uncertainty. The method is based on parameter space approach and utilizes a geometric approach to find
quadrilateral uncertainty regions in the parameter space for a fixed frequency. The uncertainty region in
the parameter plane is then determined by gridding over frequency. Since only four points are used to
determine the uncertainty regions at fixed frequencies the proposed method is fast but conservative.
