“…In T-S fuzzy model, some local linear systems can be interpolated by the so-called membership functions in a unit framework. In the past few decades, the problem of stability analysis and controller synthesis by the utilization of T-S fuzzy models has been widely investigated (see, for example, Feng, 3 Liu et al, 4 Su et al, 5 Lam and Lauber, 6 Liu et al, 7 Wu et al, 8 and Wei et al 9 and references therein). As an impactful control methodology in control systems, passivity control has been successfully applied in engineering applications, such as electrical circuit systems, mechanical systems, and complex network systems.…”
