A Codesign Methodology for Constrained Networked Systems With Frequency Specifications

This brief addresses a controller/fault detector and scheduling protocol codesign scheme in the finite frequency domain for a class of constrained networked systems. By considering the data transmission in both sensor-control center and control center-actuator channels, a switched stochastic system is first modeled. With the aid of the mode-dependent average dwell time, sufficient conditions are subsequently investigated to capture the desired performances including the finite frequency one, in which the relationship between the node accessing rate and the performances is developed. Then, node-dependent controller/fault detectors and the scheduling protocol are codesigned by the derived conditions. Finally, an application to the High Alpha Research Vehicle (HASV) is given to illustrate the effectiveness of the proposed scheme.
