| 摘 要： | 针对一类状态不可测的单输入单输出非线性不确定系统，提出了一种基于观测器的混合直接自适应模糊辨识与控制方法。设计中，将观测器、直接自适应模糊控制器与白适应模糊辨识模型相结合，用跟踪误差估计和辨识误差去调整系统的参数，以取得更好的逼近和跟踪效果。基于Lyapunov方法，证明了闭环系统的稳定性，跟踪误差渐近收敛剑零点的一个小邻域内，仿真结果验证了该方法的有效性。

| Abstract: | An observer-based hybrid direct adaptive fuzzy identification and control method was proposed for a class of single-input single-output nonlinear systems,which worked on condition that input states were not available for measurement.Since this method combined direct adaptive fuzzy control and adaptive fuzzy model with observer in design,utilizing two types of errors(estimate tracking error and identification error),which not only made system output follow a bounded reference signal,but also obtained a good ... |
