Output feedback stabilization for networked control systems with quantized fading actuating channels

This paper is concerned about the problem of output feedback quadratic mean square stabilization for control systems with a quantized fading actuating channel. An observer-based output feedback controller is derived by solving some algebraic Riccati equations, together with an inequality. It is shown that stabilizing a system through a quantized fading actuating channel by output feedback is closely related to both the absolute product of unstable poles of the system and the uncertainties generated by the communication channel. A numerical example is included to illustrate the present results.
