| 摘 要： | 针对一类状态不可测的SISO非线性不确定系统,提出一种新的模糊自适应Backstepping输出反馈控制,利用模糊逻辑系统逼近未知非线性函数,设计模糊自适应高增益观测器对系统未知状态进行观测,利用模糊自适应Backstepping控制方法设计模糊自适应输出反馈控制器。通过理论分析证明了闭环系统是半全局一致最终有界的;观测误差和跟踪误差都分别收敛到零的一个小邻域内。

| Abstract: | An adaptive fuzzy backstepping output-feedback control approach was proposed for a class of SISO nonlinear systems with completely unknown functions and without the measurements of states.Fuzzy logic systems were employed to approximate the unknown nonlinear functions,and an adaptive high-gain observer was developed to estimate the unmeasured states.Using the designed high-gain observer,and combining the fuzzy adaptive control theory with backstepping approach,a novel adaptive fuzzy backstepping output-feed... |
