Quasi-synchronization of heterogeneous dynamical networks with sampled-data and input saturation

This paper considers the problem of quasi-synchronization of heterogeneous dynamical networks with sampled-data and input saturation constrains. By introducing a leader and designing the controller involved the quantization and actuator saturation, the heterogeneous dynamical networks can be transformed into the corresponding error systems with bounded disturbances. A sufficient criterion ensuring the error system can exponentially stable and convergent to a bounded region is established via a Lyapunov functional approach. Based on the criterion, the control gain matrix is further designed. Simulation examples are presented to illustrate the validity of the theoretical results. (C) 2019 Elsevier B.V.
