| 提出一类非线性不确定系统基于最小二乘支持向量机的自适应H∞控制方法. 该方法基于最小二乘支持向量机估计对象的未知非线性函数, 并给出了最小二乘支持向量机权向量和偏移值的在线学习规则. 引入H∞控制器用于减弱外部干扰及最小二乘支持向量机近似误差对输出误差的影响. 利用李亚普诺夫理论证明了整个闭环系统一致最终有界稳定. 仿真结果表明了该方法的有效性. |
| 英文摘要 |
| An adaptive H-Infinity control based on least squares support-vector-machines(LS–SVM) is presented for a class of nonlinear uncertain systems. In this method, the LS–SVM is employed to approximate unknown nonlinear functions in the plant; and the online learning rule for the weighting vector and the bias is derived. H-infinity control is used to attenuate the tracking error caused by LS–SVM approximation and external disturbance. Lyapunov theory is used to prove the uniform ultimate bounded stability of the close-loop system. Numerical simulations are presented to show the effectiveness of the proposed method. |
