Static output feedback controller for nonlinear interconnected systems : fuzzy logic approach

This paper discusses the robust decentralized static output feedback stabilization for nonlinear interconnected systems with parametric uncertainties. Each subsystems of interconnected systems are described by Takagi-Sugeno(T-S) fuzzy models. From T-S fuzzy models, it designs the controllers of each subsystems by parallel distributed compensation. For robust stabilization of interconnect systems, sufficient conditions are derived to obtain the values of controller gains and represented to linear matrix inequalities(LMIs). An example is given to show the experimentally verification discussed throughout the paper.
