| 摘 要： | 针对状态不可测的单输入单输出非线性不确定系统,提出一种基于最小二乘支持向量机(LS-SVM)的直接自适应输出反馈控制方法.该方法首先设计一种误差观测器,间接地估计出系统的状态,然后采用最小二乘支持向量机构造自适应控制器,控制器参数的在线调整规律由李亚普诺夫稳定性理论导出.文中严格证明了闭环系统的渐近稳定性,仿真研究表明了此控制方法的可行性和有效性. |

| Abstract: | This paper presents a design scheme of least squares support vector machines(LS-SVM) based direct adaptive output feedback control for nonlinear uncertain systems with unmeasured states.Firstly the proposed method designs a class of error observer to estimate the system state indirectly,then the adaptive outout feedback controller was constructed using LS-SVM.The parameters of the controller were changed according to a law derived using Lyapunov stability theory.The asymptotic stability of the close-loop sy... |
