Robust Observer-based Fuzzy Control for Variable Speed Wind Power System: LMI Approach

Hwa Chang Sung, Jin Bae Park*, and Young Hoon Joo

Abstract

In this paper, the output-feedback control for stabilizing the uncertain nonlinear system is proposed. For achieving the robust stability, we deal with the parametric uncertainties of the concerned system which is based on the Takagi-Sugeno (T-S) fuzzy model. Also, we derive the observer-based models preserving the property and structure of the uncertainties. The sufficient conditions for output feedback stabilizing controller designs are given in terms of solutions to a set of linear matrix inequali-ties (LMIs). The simulation results for variable speed wind power (VSWP) system are demonstrated to visualize the feasibility of the proposed method.

Keywords Linear matrix inequalities (LMIs), observer-based control, parametric uncertainties, Takagi-Sugeno (T-S) fuzzy model, variable speed wind power (VSWP) system.
