Self-adaptive control of nonlinear systems based on least squares support vector machines dynamic inversion. (Chinese. English summary) Zbl 1265.93139

Summary: A method of self-adaptive control for nonlinear systems based on Least Squares Support Vector Machines (LS-SVM) dynamic inversion is presented. The method cascades the dynamic inversion model approximated by LS-SVM with the original system to get the composite pseudo-linear system. The online learning while controlling LS-SVM is used to self-adaptively compensate the inversion error of nonlinear systems which may be due to modeling uncertainties and disturbances. The updating rule of LS-SVM weights is derived from Lyapunov stability theory, and the stability of the designed system is proved. Simulation results demonstrate the effectiveness of the proposed method.
