中文摘要
      对非线性不确定性系统, 提出一种鲁棒滑模观测器. 所提出的鲁棒滑模观测器通过滑模与相应的控制策略 来实现, 设计参数的选取不需要求解大量方程, 同时能保证对系统的非线性不确定项具有鲁棒性. 通过设计滑模, 可以调整观测器跟踪系统状态的收敛速度, 使状态估计达到预期的指标. 仿真结果验证了提出方法的有效性.
英文摘要
      A robust sliding mode observer for nonlinear and uncertain systems is proposed in this paper. Firstly, the state observer problem is formulated. Then, the sliding mode and control strategy are designed, which guarantees the robustness of the observer whith the nonlinearities or uncertainties of systems. The convergence rate between the observer and the system can also be adjusted by choosing suitable sliding mode manifold, so as to attain the desired performances. Finally, simulation results are presented to validate the design.
