摘要
针对无线网络中的高度非线性问题建立基于T-S模糊模型的连续控制系统,并考虑到网络中的状态时滞和不确定性,对于网络通信信道的压力问题引入对数量化器,同时为了提高无线网络控制系统的稳定性,引入模糊动态输出反馈,最终给出无线网络控制系统的量化输出反馈控制器的设计方法,并以LMI(线性矩阵不等式)形式描述,同时以数值例子说明设计方法的有效性。
Wireless networked control system has a series of characteristics such as high nonlinearity, delay, packet loss and uncertainty. According to the highly nonlinearity, state delay and uncertainty in wireless networks, a continuous control system based on T-S fuzzy model was established in this paper. A logarithmic quantizer was introduced to deal with the pressure of network communication channel. At the same time, in order to improve the stability of wireless network control system, fuzzy dynamic output feedback was introduced. Finally, the design method of quantized output feedback controller for wireless networked control system was presented in the form of linear matrix inequality （LMI）. In addition, a numerical example is given to illustrate the effectiveness of the designing method.
