H ∞ Observer-Based Sliding Mode Control for Uncertain Stochastic Systems with Time-Varying Delays

Abstract EN

The paper is concerned with sliding mode control for uncertain time-delay systems subjected to input nonlinearity and stochastic perturbations.

Using the sliding mode control, a robust law is derived toguarantee the reachability of the sliding surface in a finite time interval.

The sufficient conditions on asymptotic stability of the error system and sliding mode dynamics with disturbance attenuation level are presented in terms of linear matrix inequalities (LMIs).

Finally, an example is provided to illustrate the efficiency and effectiveness of the proposed method.
