【摘要】 采用T-S模糊模型描述离散混沌系统,将离散混沌系统模糊化为局部线性模型,依据Lyapunov稳定性定理和线性系统滑模控制趋近律设计方法,设计了一种新型的离散滑模控制器。该控制器不仅能保证局部线性模型渐近稳定,而且能确保模糊动态模型全局渐近稳定。利用Matlab对确定Henon系统和不确定Henon系统进行了数值仿真,结果表明:所设计的控制器不但有效,而且具备很强的鲁棒性。更多还原

【Abstract】 The discrete chaotic system was described and converted into a local linear model with fuzzy method based on T-S fuzzy models.On the basis of Lyapunov stability theorem and approaching law method,a novel sliding mode controller was designed.The controller can insure the stability of global fuzzy model.The controlled certain and uncertain Henon systems were simulated with Matlab.The numerical results demonstrate the validity and robustness of the control scheme.更多还原
