Application of D-K Iteration Technique Based on H∞ Robust Control Theory for Power System Stabilizer Design

Abstract

The D-K iteration method of controller design combines H∞ synthesis that ensure robustness and µ-analysis that takes care of parametric uncertainties, and yields a good performance of the robust controller. The idea is basically to find a controller that minimizes the peak value over frequency of the upper bound on µ. This robust control technique is applied for the Power System Stabilizer design for a Single Machine Infinite Bus (SMIB) system, which has already proved to be a successful tool in mitigating low
