To the widely existed characteristics of time-delay, non-linear and timevarying of parameters in the industry process, an adaptive neuron-fuzzy PID controller based on optimal prediction is presented.

Then a fuzzy logic controller was designed as a regulator to modify the optimal control gains based on the run-time information, including navigation, communication, mission priority, and so on.

A fuzzy controller is designed to decide the optimal tactic of distributing the information flow of the queue system, which makes the time of the clients delay least in the communication system.
