| 摘 要： | 根据二级电压控制的原理和网络传输的特点,建立了同时考虑不确定信息延迟、数据包丢失和乱序的网络化二级电压控制NSVC(networked secondary voltage control)模型,运用线性矩阵不等式LMI(linear matrix inequality)方法设计了具有鲁棒容错特性的二级电压控制器,能保证控制系统在网络环境下具有良好的控制性能和稳定性。以经典3机系统为例进行数字仿真,验证了该网络化二级电压控制器的性能和效果。

| Abstract: | According to the principle secondary voltage control and characteristics of network transmission,the networked secondary voltage control(NSVC) model is proposed considering uncertain time-delay,data dropout and data packet disorder.By means of the linear matrix inequality(LMI),the design methods of robust fault-tolerant NSVC controller is given which can ensure the stability and control performance under network environment.The operation performance of the proposed NSVC scheme is analyzed and the simulation results on the classic 3-generator system are presented to illustrate the validity and effectiveness of the proposed control scheme. |
