摘要：
A sufficient condition for a general nonlinear stochastic system to have L-2 - L-infinity gain less than or equal to a prescribed positive number is established in terms of a certain Hamilton-Jacobi inequality (HJI). Based on this criterion, the existence of an L-2 - L-infinity filter is given by a second-order nonlinear HJI, and the filter matrices can be obtained by solving such an HJI.
