Uncertain nonlinear systems refer to the existence of various uncertainty factors in the control system, such as model uncertainty, external disturbance, sensor noise, etc. These factors may lead to system instability or control performance degradation, so measures need to be taken to ensure system stability and control performance.This paper will introduce the research on the simultaneous stability and H∞ control of uncertain nonlinear systems. Firstly, the stability problem of uncertain nonlinear system and its solution methods will be introduced, including small perturbation stability, Lyapunov stability and LMI stability, etc. Secondly, the H∞ control theory and its application in uncertain systems will be introduced, including the design method of H∞ controller, the calculation method of H∞ 精品文档---下载后可任意编辑performance index, the application of H∞ control in filter design, etc. Finally, the problem of simultaneous stability and H∞ control will be introduced, including the design method, performance analysis and optimization algorithm, and some practical application cases will be given.Keywords: uncertain systems, stability, H∞ control, control performance, optimization algorithm
