【摘要】 研究一类基于事件触发的非线性系统的H∞模糊跟踪控制问题。利用T-S模糊模型来对非线性被控对象进行处理。利用离散化处理方法,建立了离散时间非线性系统的跟踪控制模型,并基于Lyapunov稳定性理论,以LMIs的形式提出一种状态反馈H∞模糊跟踪控制器设计方法,并保证在给定跟踪性能要求下被控对象的状态能较好地跟踪给定模型的状态。最后,通过数值仿真表明了所提方法是可行的。更多还原

【Abstract】 This paper investigates the fuzzy H∞ tracking control problem for a class of nonlinear systems via the TakagiSugeno(T-S) fuzzy model.Introducing a novel discrete event-triggered communication scheme,a new fuzzy H∞tracking model of nonlinear systems is established.Based on a fuzzy Lyapunov function approach,a co-design method for tracking feedback control gain and trigger parameters that guarantee the prescribed H∞tracking performance of nonlinear systems is derived in terms of LMIs.Finally,a numerical example is given to show the effectiveness of the proposed method.更多还原
