| 摘 要： | 针对已有的网络控制系统中的传输时延统计计算量较大,运算较复杂等问题,设计了具有时延补偿功能的状态观测器对其进行补偿,并利用LMI(Linear Matrix Inequality)方法得出了控制律,对闭环系统进行了稳定性分析.仿真试验表明,所提补偿方案能够有效地补偿时延对系统性能的影响,且补偿精确度高,计算量减少.

| Abstract: | With the more and more larger scale of the control systems, many control systems are constructed as networks through fieldbus technology. The information such as sensor signals and controller signals are transferred through the network. Because of the limitations of communication bandwidth and information collision, it is inevitable that there exists time delay in the Networked Control System. According to the transmitted time-delay, a kind of state-observer with the ability to compensate time-delay is designed, and the control law is achieved using the Linear Matrix Inequality method. Then the stability of the closed-loop system is analyzed. The result of the simulation experiment shows the validity of the proposed method. |
