Support Vector Regression (SVR), featured as being capable of effectively avoiding over learning and local minimum, and getting global optimal solution, is a new method for model control problems. In combination with input-output linearization, an algorithm of feedback linearization-based SVR is proposed with inverse dynamic model and compensation term for the inversion error identified off-line. Then the inverse model is used as a controller to constitute an adaptive inverse control system. Parameters of SVR are optimized by K-fold Cross Validation algorithm. Finally, numerical simulations are conducted for predefined reference on the platform of Matlab, showing that the proposed control scheme has good performance of dynamic response and control effect.
