Abstract: To deal with the control problems of non-linear system，a new Generalized Predictive Control（GPC） algorithm based on Support Vector Machine（SVM） inverse control is proposed.The SVM is applied to identify the αth-order inverse model of the controlled plant，which is cascaded before the original system to creat a pesudo-linear sub-system.And then for the simply pesudo-linear sub-system the generalized predictive control algorithm can be used.Simulation results of a typical non-linear system show that the presented method can accurately model the inverse dynamic system，and has the characteristics of great tracking accuracy，better robustness stability，and anti-disturbance ability.
