| 摘 要： | 首先建立一种动态T-S模糊子系统,用于估计非线性系统,然后设计一种稳定的参考模型,其前件与T-S模糊子系统相同.在此基础上,提出一种反馈控制器,其控制矩阵采用线性矩阵不等式(LMI)的方法进行求解,使得在数学模型已知的情况下,闭环系统渐近稳定.此外,为补偿和消除实际系统中常存在的参数不确定性和外部干扰的影响,进一步提出...

| Abstract: | Some dynamic T-S fuzzy subsystems were presented to approximate a nonlinear system.The stable reference model with the same fuzzy sets as those of the T-S fuzzy subsystems rule was established.To make the states of the closed-loop system follow those of the reference modela,feedback controller was designed.The control gain can be solved by LMI approach.The closed-loop systems can be stable when the exact models are known.To compensate and eliminate the pa-rameter uncertainty and disturbance usually existing... |
