Model-based robust control for nonlinear networked control systems

Abstract

In this chapter, a nonlinear model-based networked control system (MB-NCS) will be proposed to reduce the packet rate and network usage. A model plant that approximates the nonlinear plant dynamics via a transmission attenuation path and makes possible stabilization of the nonlinear plant will be introduced. The comparison system whose states as well as the nonlinear MB-NCS states will be developed such that the stability of the original system can be guaranteed. And then the robust stabilization problems of the nonlinear time-variant MB-NCS with time-variant transmission attenuation will be investigated. Finally, an example with simulation results is given to exemplify the implementation of the proposed controller design technique. © 2013 Springer Science+Business Media New York.
