Abstract:
An internal model networked control strategy based on the model reference adaptation was proposed for the networked control system to solve problem of time delay and the inaccuracy of the model. With the internal model controller as the regulator, the fuzzy logic control module was as an adaptive mechanism, the networked controller was designed according to the time-delay prediction. The performance of the networked control system was improved by combining the advantages of adaptive control, fuzzy control and internal model control method. Finally, the most representative first-order and second-order systems in the field of industrial process control were taken as controlled objects and simulated by the proposed strategy. The results show that the stability and anti-jamming ability of the system are obviously improved by the proposed strategy, which verifies the correctness and effectiveness of the proposed strategy.
