Abstract: Since various unpredictable disturbances are found in the actual system, it is difficult for the system to accurately achieve the expected performance. Therefore, the probability constraint H_∞ performance is used to make the system more suitable for practical engineering applications. In order to avoid network congestion and resource occupation, RR protocol is introduced to schedule data transmission between network nodes. The filter of probability-guaranteed and non-fragile is constructed. The uncertain parameters of the system are controlled by random variables, which are uniformly distributed and independent of each other. The filter that can guarantee performance requirements under probability constraints is designed by seeking a parameter box. The probability-guaranteed H∞ filtering problem is solved by recursive matrix inequality. Finally, the effectiveness of the filtering scheme is verified by a simulation example. 

Key words: probability-guaranteed, round-robin protocol, nonlinear, non-fragile
