“…In these works, backstepping-based second-order SMC [9], backstepping-based adaptive SMC [6] have been used to control the NH systems in presence of uncertainties. Moreover, in [2,21,24,34,36], TSMC has been proposed for stabilizing the NH systems with chained form of state equations. In addition, the intelligent control strategies such as fuzzy and neural controllers and their combinations with SMC-based methods have also been widely proposed for trajectory tracking problems [5, 8, 15, 25-27, 32, 42].…”
