Abstract :
The article concerns linear systems which are subject to both time-varying norm-bounded parameter uncertainty and exogenous disturbance. It addresses the robust H∞ control problem of designing a linear dynamic output feedback controller such that the closed-loop system is quadratically stable and achieves a prescribed level of disturbance attenuation for all admissible parameter uncertainties. It is shown that such a problem is equivalent to a scaled H∞ control problem
