Research ArticleOpen accessIn the keywordsDesign of Robust UPFC Controller Using H∞ Control Theory in Electric Power SystemSeyed Abbas Taher, Shahabeddin Akbari, Ali Abdolalipour, Reza HemattiAn industrial plant, such a power system, always contains parametric uncertainties. In the design of a controller the uncertainties have to be considered. Otherwise, if the real plant differs from the assumed plant model, a controller, designed based on classical controller design approaches, may not ensure the stability of the overall system. In this paper design of robust control for … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,090 accessesView PDFCite
