Modeling and simulation of a nonlinear system under networks

A simulation framework based on modeling of a nonlinear system under a networked control system structure was proposed according to the nonlinear systems with uncertainties, complex structure, modeling difficulty and hard simulation study under networks. On the basis of Matlab/Simulink modularization modeling of two inverted pendulums coupled by a spring and TrueTime network block, the uncertainties of the plant system and network-induced delays were disposed by a decentralized robust controller synthetically. The simulation results show that the proposed framework not only reduces the complexity of nonlinear system modeling, but also provides the basis for the research of a nonlinear system having a networked control system structure.
