Finite-time attitude tracking control for a rigid spacecraft using time-varying terminal sliding mode techniques

Distributed adaptive containment control for second-order multi-agent systems via NTSM

“…Figure 7 shows the response curves of control law for followers 1 to 3, and the chattering is eliminated. The above simulation results show that the proposed control laws (8) and (20) can both provide good robustness against the unknown external disturbances.…”

“…Figure 5 gives the trajectories of agents 1 to 7 by using control law (20), which shows that followers 1 to 3 move into the convex hull formed by leaders 4 to 7. Figure 6 shows the response curves of errors Figure 5: Trajectories of agents 1 to 7 using control law (20). The circles and squares represent the leaders and the followers, respectively.…”

“…Figure 4 shows the response curves of control law for followers 1 to 3, and the chattering is eliminated. For the control law (20), we choose the same parameters with control law (8). Figure 5 gives the trajectories of agents 1 to 7 by using control law (20), which shows that followers 1 to 3 move into the convex hull formed by leaders 4 to 7.…”

Design of sliding-mode observer for a class of uncertain neutral stochastic systems

“…Conversely, SMC (Ahmad, & Zhu, 2015;Utikin, 1992), because of its various attractive features such as quick response, good transient performance, particularly, the valuable invariance against matched uncertainties, has been well known as an effective robust control strategy and also has found to be widely applied to various complex systems (Basin, Ferreira, & Fridman, 2007;Liu, & Gao, 2016;Wu, & Lam, 2008;Zhao, & Zhu, 2014) as well in many technical problems (Zhao, & Jia, 2015). As for the neutral systems, some excellent works have been reported.…”
