摘要: 支持向量机(SVM)是一种基于结构风险最小化(SRM)的新的机器学习方法,具有良好的推广性能。给出了利用其构造逆控制器的方法,并将逆控制器串联于原系统前构成伪线性复合系统。针对此开环逆控制系统,在核函数为局部Lipschitz的前提下,证明了控制器是有限增益稳定的,并给出Gaussian核函数对任一变量的局部Lipschitz性的充分条件,在一定合理的假设下给出了控制系统的稳定性结论。

Abstract: Support Vector Machines (SVM) is a new machine learning method on Structural Risk Minimization (SRM) with good generability. The method of constructing inverse controller using SVM was given in this paper. A pseudo-linear compound system was formed when cascading with the inverse controller before the original system. The finite-gain stability of the controller was proved under the assumption that the kernel function was local Lipschitz in this open-loop inverse control system. The sufficient condition for that Gaussian kernel function to the local Lipschitz of either variable was given. The stability of the whole system was also proved under some proper assumptions.
