Packet-Based Control for Networked Hammerstein Systems

This chapter extends the application of the packet-based control approach proposed in Chap. to a class of input nonlinear systems described by a Hammerstein model, where a static nonlinear input process is present in the system. A “two-step” approach is adopted to separate the nonlinear input process from the system so that the packet-based control approach can be applied to such systems with minor modifications. Two descriptions of the Hammerstein model, i.e. the input-output description and the state-space description, are considered, where the stability analysis of the former in the case of arbitrary delays proved to be a difficulty due to the constraints of the Popov criterion, while it is solved in the more generalized state-space description by using switched system theory.
