【Abstract】 The adaptive Smith generalized predictive controller is employed to improve the dynamic behavior of the time delay system. Predictive model is constituted by Smith predictor that makes up of identifiable parameters using RFF(recursive forgetting factor) method, based on the model matching on the frequency of zero. The simulation results show that the method is effective when time delay and parameters change slowly.\;更多还原
