In this study a robust controller is proposed to provide a robust performance under system
uncertainties through static compensator (STATCOM) devices. The method of multiplicative uncertainty has
been employed to model the variations of the operating conditions in the system. A Quantitative Feedback
Theory (QFT) method based on loop shaping is employed to select a suitable open-loop transfer function. The
design is carried out by applying robustness criteria for stability and performance. In order to show the
effectiveness of our proposed controllers, the proposed controllers have been compared with classical
controllers. The robust controller design has been demonstrated to provide extremely good dynamic
performance over a range of operating conditions.
Key words: Flexible AC transmission systems, robust control, static compensator, system uncertainties, , ,
