Synchronization of the Coupled Distributed Parameter System with Time Delay via Proportional-Spatial Derivative Control

Abstract EN

By combining parabolic partial differential equation (PDE) theory with Lyapunov technique, the synchronization is studied for a class of coupled distributed parameter systems (DPS) described by PDEs.

First, based on Kronecker product and Lyapunov functional, some easy-to-test sufficient condition is given to ensure the synchronization of coupled DPS with time delay.

Secondly, in the case that the whole coupled system cannot synchronize by itself, the proportional-spatial derivative (P-sD) state feedback controller is designed and applied to force the network to synchronize.

The sufficient condition on the existence of synchronization controller is given in terms of a set of linear matrix inequalities.

Finally, the effectiveness of the proposed control design methodology is demonstrated in numerical simulations.
