Nonlinear Predictive Control for Multivariable System Using RBF - ARX Model
摘要
Abstract
A nonlinear predictive control algorithm was proposed for multivariable die-casting processes of die-casting machine based on RBF - ARX model. By constructed global nonlinear dynamic RBF - ARX model referenced on historical data and mechanism model.the structured nonlinear parameter optimization method is developed to estimate and optimize parameters of RBF- ARX model off-line,finally determined the predictive system structure and steps forward output. Speed set point tracking comparison with traditional PID control shows nonlinear predictive control algorithm based on RBF - ARX model has good dynamic characteristics and high control precision.关键词
