Abstract :
New robustness results are presented. Both structured and unstructured parameter bounds are improved for continuous systems, the L∞ bounds on output are given for continuous-time systems subject to L2 disturbance inputs. These results are all explicitly related to the state covariance matrix. The robustness properties of any covariance controller that gives a specified state covariance to the closed-loop system are described
