Distributed Control System Consistency Control Method Research

For large distributed control system in the process control signal node conflict, cause delay, not synchronous control.Put forward a kind of nonlinear coupled with the control algorithm, through the node consistency of different module, communication model between the consistency of communication is calculated.By relational decision theory of communication results in communication appear to estimate, time delay of state, can ensure the consistency of communication signals.Make many system can delay allowed in the error in communication.Effectively solve the communication appeared in the process of delay, and signal with the problem.Experiments show that the nonlinear coupling with the consistency of the algorithm of the group, make all the individual can achieve a specified value in advance.To solve nonlinear coupling with the consistency of the problems, has made the good results.
