“…Thus, it is theoretically and practically important to study the dynamical systems with time delay. To date, many researchers have invested a lot of time and effort to investigate the problem of stability analysis for TDSs in the real engineering systems, such as singular systems, 4,5 Markov jump systems, 6,7 synchronization issues, 8,9 sliding mode control, 10 robust nonfragile filtering, 11 H ∞ tracking, 12 uncertain neural networks, 13 and other scientific areas. 14,15 The existing results of TDSs can be classified into 2 categories: delay-independent and delay-dependent ones.…”
