Abstract

A class of hybrid uncertain system and its uncertainty boundary are put forward in respect to nonlinearity and uncertainty of power systems with STATCOM (static synchronous compensator). The design method of robust H∞ controller for the system is given and applied to four-node multi-machine power system with STATCOM. Decentralized robust controller for STATCOM and excitation of generators is designed. The simulation results verify effectiveness of the controller.
