Fuzzy Dynamic Matrix Control Based on Selective Self-tuning

A scheme of fuzzy dynamic matrix control(DMC)based on selective self-tuning is proposed to solve the problem of uncertainty of the mismatched model.In the presence of bad mismatched model,the least-square method is employed to identify the model since the DMC cannot get good performance.In order to get more precise model,the process of identification avoids the effect of the disturbance.In addition,fuzzy control is introduced to adjust the parameter of the feedback correction.The effectiveness of the proposed method is verified by the simulation results for a non-minimum-phase plant with time delay.
