Novel Dropout Compensation Control Design for Networked Control Systems With Mixed Delays

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.
