摘要: 针对实际系统存在各种不可预知的扰动, 造成系统很难精确地达到期望的各项性能指标, 研究了基于 Round-Robin 协议的一类非线性时变系统的保概率 H 滤波问题。 利用概率约束 H 性能指标, 使该系统更贴近实际工程应用。 同时, 考虑在数据传输过程中产生的网络拥塞和资源占用现象, 采用 Round-Robin 协议对网络节点间的数据传输进行调度。 考虑信号从传感器至待设计滤波器传输过程中具有非线性扰动, 构造保概率非脆弱 H 滤波器。 其不确定参数由服从均匀分布且相互独立的随机变量控制, 同时通过寻求线性矩阵不等式工箱设计能在概率约束下保证性能要求的滤波器。 利用递推线性矩阵不等式方法求解保概率 H 滤波问题。最后, 通过仿真示例, 证明所提出的滤波方案的有效性。

关键词: 保概率, Round-Robin 协议, 非线性, 非脆弱

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
