| 摘 要： | 针对一类具有块三角形式的多输入多输出(MIMO)非线性不确定系统,基于Backstepping设计研究该系统的自适应模糊输出跟踪控制问题。模糊逻辑系统用作逼近系统的未知函数。通过理论分析,证明闭环系统是半全局一致终结有界的;跟踪误差收敛到一个小的残差集内。仿真结果表明了该方法的有效性。

| Abstract: | The adaptive fuzzy output tracking control problem was discussed for a class of uncertain multi-input /multi-output(MIMO) nonlinear systems with the block-triangular structure via Backstepping.The fuzzy logic systems were used to approximate the unknown nonlinear functions.Through theoretical analysis,the closed-loop control system was proven to be semiglobal1y and uniformly,ultimately bounded,with tracking error converging to a residual set.Simulation results demonstrated the effectiveness of this approach. |
