Abstract :
Addresses the problems of robust ℋ∞ performance analysis and control synthesis for linear systems subject to uncertain real time-varying parameters. The uncertain parameters enter affinely in the matrices of the system state-space model and the admissible values of the parameters and their rates of variation are supposed to belong to a given polytope. New LMI based methods of robust ℋ∞ analysis and control design via state feedback are proposed using parameter-dependent Lyapunov functions
