能量约束的网络控制系统的H∞滤波

Filtering for networked control systems with communication energy constraint

考虑传感器节点存在能量约束问题,研究了一类能量约束的网络控制系统滤波器设计方法。首先,利用贝努利序列搭建传感器节点不同能量级调用的情况,将系统建模为带有随机变量的闭环控制系统。在此基础上,以LMIs形式给出滤波误差系统随机稳定的条件。最后通过数值仿真验证了所提算法的有效性。

Considering the problem of sensor nodes with energy constraint, the method of filtering for networked control systems with energy constraint was studied. First of all, different energy level of the sensor nodes are modeled by a Bernoulli random sequence and filtering error system is modeled closed - loop system with stochastic parameter. Based on this, the stochastic stability condition for filtering error system are provided in terms of LMIs. Finally, an example is given to illustrate the effectiveness of the proposed method.
