Abstract:

Aim at the NCS with data packet dropout and network-induced time delay, a new modeling method was proposed. With data-packet dropouts rate constant, according to information vary which controller update, two different schemes were adopted. Two models of asynchronours dynamical system of NCS were set up respectively, and sufficient conditions for the exponentially stability of the two different closed NCS models were derived. Simulation examples were given to illustrate the validity of the results.
