摘要：
In this paper the problem of non-fragile adaptive sliding mode observer design is addressed for a class of nonlinear fractional-order time-delay systems with uncertainties, external disturbance, exogenous noise, and input nonlinearity. An H-infinity observer-based adaptive sliding mode control considering the non-fragility of the observer is proposed for this system. The sufficient asymptotic stability conditions are derived in the form of linear matrix inequalities. It is proven that the sliding surface is reachable in finite time. An illustrative example is provided which corroborates the effectiveness of the theoretical results.
