Abstract

The focus in this paper is on compensation for sensor faults. Virtual sensors or compensation using the YJBK controller architecture (after Youla, Jabr, Bongiorno and Kucera) are two ways to compensate sensor faults without changing the nominal controller directly. Design of virtual sensors is quite simple due to the separation between the nominal controller and the virtual sensor. A short analysis of the virtual sensor in connection with the YJBK controller architecture is given.
Further, a reformulation of the YJBK controller architecture is given and the connection with the Bezout equation is described. It is shown that this new formulation makes it easy to change the sensors in the system without changing the nominal controller, but only extend the included system matrices. System uncertainties in connection with sensor faults will also be considered in connection with the YJBK controller architecture.
