中文摘要

It is presented, in this paper, a novel adaptive sliding mode observer (ASMO) for reconstructing the states of nonlinear stochastic
systems with structure uncertainties, parameter perturbations and external disturbances which is presented in the Ito differential equations.
The proposed ASMO uses sliding mode technique to guarantee the robustness of observation, and an adaptive law is employed to update the
sliding mode gain. The estimation error of the proposed observer is theoretically proved to be mean square exponentially convergent to a
limited bound. A simulation studies are made on computer with MatLab for reconstructing the states of Lorenz chaotic attractor with
uncertainties and polluted by noises, and the simulation results verify the effectiveness of the proposed observation strategy
