When a white noise interferes with the controller, a time series autoregressive (AR) model is built using the sampled experimental data.

To avoid interfering by work, data were sampled through a multi-layers network which synthesize the field-bus and Ethernet and center on programmable logic controller.

Considering the modeling error between fuzzy model and practical plant, it is a challenging issue to design fuzzy sampled-data controller for uncertain fuzzy systems.
