Packet-Based Control for Networked Wiener Systems

Abstract

Following the extension of the packet-based control approach to networked Hammerstein systems in Chap. 3, another extension readily follows which is the category of output nonlinear systems described by the Wiener model, where a static nonlinear output process is present in the system. For this type of nonlinear systems, the two-step approach proposed in Chap. 3 can still be applied to separate the nonlinear process from the system, thus enabling the packet-based control approach to be implemented in this case. Different from the input nonlinearity case, a specially designed observer is proposed for the implementation of the two-step approach to networked Wiener systems, and as a result, the stability criterion of the corresponding closed-loop system depends not only on the communication conditions but the error of the observer.
