Output regulation for switched discrete-time systems with output signal quantization

Abstract

This paper investigates the output regulation problem for switched discrete-time systems with output quantization. We adopt the quantized output in feedback controllers and allow each subsystem to have its own quantization density, so that the communication network can be efficiently utilized. By using the different coordinates transformation, the solvability of the output regulation problem is guaranteed under deigned output feedback controllers with the switching signals satisfying a dwell time constraint. In the simulation, a pulse-width modulation driven boost converter model is employed to validate the result.

Output Regulation of Switched Stochastic Systems with Sampled-Data Control

“…Wang et al have constructed a class of multiple linear Lyapunov functions and solved the ORP of positive switched systems by designing two kinds of controllers [22]. Reference [23] discusses the solvability of the ORP for discrete switched systems, and in order to utilize the communication network effectively, the designed feedback controller adopts the quantized output, and the solution to the problem is given by different coordinate transformations. There are still many problems of output regulation of switched systems to be studied.…”
