Abstract: | Robust H∞ control design for linear systems with uncertainty in both the state and input matrices is treated. A state feedback control design which stabilizes the plant and guarantees an H∞-norm bound constraint on disturbance attenuation for all admissible uncertainties is presented. The robust H∞ control problem is solved via the notion of quadratic stabilization with an H∞ -norm bound. Necessary and sufficient conditions for quadratic stabilization with an H∞-norm bound are derived. The results can be regarded as extensions of existing results on H∞ control and robust stabilization of uncertain linear systems |
