Decentralized Guaranteed Cost Control for the Singular Interconnected Large-Scale Systems with Parameter Uncertainty

For the singular interconnected large-scale systems with uncertainties satisfied the norm-bounded time-invariant, directly from the start of each subsystem-study its decentralized guaranteed cost control. Give a sufficient condition of the existence of the decentralized guaranteed cost controller. The design of the decentralized guaranteed cost controller is converted into solving the feasible solution of a linear matrix inequality. Then using feasp function of matlab toolbox we can directly seek a feasible solution. And finally an illustrate example show the effectiveness of the method.
