Direct adaptive control of a class of nonlinear systems using least squares support vector machines

A scheme of direct adaptive control for a class of nonlinear systems based on least squares support vector machines(LS-SVM) is presented, in which LS-SVM is used to construct the adaptive controller. The parameters of the adaptive controller are changed according to a law derived using Lyapunov stability theory. The asymptotic stability of the desighed system is proved. Numerical simulations show the effectiveness and feasibility of the proposed method.
