“…To name only a few, for the problems of stability analysis, in [42], there are some new results about the delay-independent approach. In [43], the authors present significant results for controller design to guarantee the exponential stability of the systems, and the results are further improved in [44]. On the other hand, in [45], conditions are presented to construct a stabilizing switching signal for constant time delay systems, which are further improved to analyze time-varying delay systems in [46].…”
