In the domain of industry process control, the model identification and predictive control of nonlinear systems are always difficult problems. To solve the problems, an identification method based on least squares support vector machines for function approximation is utilized to identify a nonlinear autoregressive external input (NARX) model. The NARX model is then used to construct a novel nonlin...Show More
