基于线性矩阵不等式技术,采用状态反馈控制,考虑同时带有网络诱导随机丢包和量化的H∞控制问题。考虑信号经网络从传感器到控制器和从控制器到执行器的传输中存在通信诱导随机丢包,并采用动态量化器量化信号。设计H∞控制器的同时,提出量化的控制策略,使得闭环系统在量化器的量化范围条件下指数均方稳定且具有指定的H∞性能指标。通过数值仿真例子表明设计方法的有效性。 Based on the linear matrix inequality technique, the state feedback control is used to consider the H∞ control problem with network induced random packet loss and quantization. Consider the existence of a communication-induced random packet loss in the transmission of signals from sensor to controller and from controller to actuator over the network, and quantify the signal using a dynamic quantizer. At the same time of designing H∞controller, a quantitative control strategy is proposed, which makes the closed-loop system mean-square stable with the specified H∞ performance index under the quantization range of the quantizer. The numerical simulation example shows the effectiveness of the design method.
