Adaptive Fuzzy Generalized Predictive Control Based on Discrete-Time T-S Fuzzy Model

The paper presents an adaptive fuzzy predictive control based on discrete-time Takagi-Sugeno (T-S) fuzzy model. The proposed controller is based on Generalized predic-tive control (GPC) algorithm, and a discrete-time T-S fuzzy model is employed to approximate the unknown non-linear process. To provide a better accuracy in identifica-tion of unknown parameters of the model, it is proposed an on-line adaptive law which ensures that the tracking error remains bounded. The stability of closed-loop control sys-tem is proved/studied via the Lyapunov stability theory. To validate the theoretical developments and to demonstrate the performance of the proposed control is simulated as nonlinear system a laboratory-scale liquid-level process. The simulation results show that the proposed method has a good performance and disturbance rejection capacity in industrial process
