To the high nonlinear and complex constrained system,it is difficult to obtain satisfying performance in model predictive control using of nonlinearity of nonlinear model and quadratic programming(QP)optimization. An algorithm of nonlinear model predictive control system based on support vector model and particle swarm optimization is proposed.The simulation result shows the generalization ability and optimization speed and ability of particle swarm optimization,and the feasibility to use it in nonlinear model predictive control is proved.
