- Abstract:
- For large-scale samples,SVM does not perform as well as neural networks and this paper tries toimprove the training speed by simplify the decision functions by matrix transform. We simplify the unnecessarysupport vectors in SVM modeling and introduce a relaxation factor in order to improve the effects of simplifica-tion.Experiment shows that the number of support vectors is redused by at least one third. Using the modelnonlinear model built by SVM after linearizing as the predictive model of predictive control. PSO was used toselect the best SVM parameters and computing the optimal control law of predictive control. The method canaccelerate the response and shorten the overshoot through a simulation of a cement rotary kiln.
