鉴于网络数字通信的特点,研究非线性网络化系统的状态量化反馈H_∞控制问题.首先,同时考虑到网络的诱导时延、数据丢包和信号量化,建立闭环系统的采样模型;然后,结合区间时滞分割法,将其转化为状态中附加两个时滞变量的分段连续模糊系统;再利用时滞系统方法和对数量化器的扇形界格式,对闭环模糊系统进行了H_∞性能分析和H_∞控制器综合;最后,通过仿真例子验证了所提方法的可行性. In view of the characteristics of network digital communication, the state quantitative feedback H_∞ control problem of nonlinear networked systems is studied.Firstly, a sampling model of closed-loop system is established, taking into account the induced delay, data packet loss and signal quantization of the network; Interval lag splitting method, which is transformed into a piecewise continuous fuzzy system with two delay variables in the state. Using the time-delay system method and the quantizer sectorial sector format, the closed-loop fuzzy system is given H_∞ performance Analysis and H_∞ controller synthesis. Finally, the feasibility of the proposed method is verified through simulation examples.
