This article develops a pinning control strategy for the finite-horizon H-infinity synchronization problem in a kind of discrete time-varying nonlinear complex dynamical network in a digital communication circumstance. A feedback-type dynamic quantizer is introduced to comply with the digitized data exchange, and a quantized pinning control scheme is applied on a small fraction of the network nodes to reduce control expenses while achieving the desired global synchronization objective. The article establishes a sufficient condition using the completing-the-square technique to ensure the finite-horizon H-infinity index of the synchronization error dynamics against quantization errors and external noises. A controller design algorithm is proposed based on an auxiliary H-2-type criterion, and the desired controller gains are obtained through two coupled backward Riccati equations. The validity of the presented results is verified through a simulation example.
In this article, a pinning control strategy is developed for the finite-horizon H-infinity synchronization problem for a kind of discrete time-varying nonlinear complex dynamical network in a digital communication circumstance. For the sake of complying with the digitized data exchange, a feedback-type dynamic quantizer is introduced to reflect the transformation from the raw signals into the discrete-valued ones. Then, a quantized pinning control scheme takes place on a small fraction of the network nodes with the hope of cutting down the control expenses while achieving the expected global synchronization objective. Subsequently, by resorting to the completing-the-square technique, a sufficient condition is established to ensure the finitehorizon H-infinity index of the synchronization error dynamics against both quantization errors and external noises. Moreover, a controller design algorithm is put forward via an auxiliary H-2-type criterion, and the desired controller gains are acquired in terms of two coupled backward Riccati equations. Finally, the validity of the presented results is verified via a simulation example.
