Novel Dropout Compensation Control Design for Networked Control Systems With Mixed Delays
针对混合时延下的网络化控制系统，提出一种新型混合丢包补偿控制方法，利用可用反馈信息主动补偿两个通信信道的数据包丢失，并构建改进的增广切换系统模型，确保随机有限时间稳定性并改善瞬态性能。
This study is to focus on the problem of finite-time control design for a class of networked control systems (NCSs) with mixed delays. First, a novel hybrid dropout compensation control method is proposed to reasonably use available system feedback information, which can actively compensate for data packet dropouts in two communication channels. Second, an improved augmented switched system model is constructed based on the mixed delays and the hybrid parameter. Then, the gain matrices that vary with the data packet dropout are formulated to ensure stochastic finite-time stability (SFTS) and improve the transient control performance of the resulting closed-loop system. The slack variables (SVs)-based algorithm is presented to reduce the computational time, and the average dwell-time switching law is determined. Finally, the obtained theoretical results are verified by a numerical example.
