T-S模糊系统事件触发传输机制H∞控制器设计
摘要
摘要:针对存在执行器故障的一类非线性网络控制系统(Nonlinear Networked Control System,NNCS),采用状态反馈控制策略,研究了事件触发机制下的H∞容错控制器设计方案。采用TS模糊模型对非线性系统进行建模,并按照李雅普诺夫稳定性理论推导出具有H∞性能的容错控制器存在的充分条件,通过合同变换求解了容错控制器。最后通过仿真算例验证所提方法的有效性。
Abstract
Abstract:To study the design of Hinfinity faulttolerantcontroller for a class of Nonlinear Networked Control Systems (NNCS) withactuator failures we use state feedback control strategy. First the nonlinearsystem is modeled as a TS fuzzy model
and then the sufficient condition forthe existence of fault tolerant controller with Hinfinity performance isderived. Then under the contract transformation
the faulttolerant controllergains are calculated. Finally
a numerical example shows the feasibility of theproposed theory.
