Control system design with dependability criterion using structural analysis

Blaise Conrard

Abstract

This paper deals with the design of control systems. The aim of the proposed method is to optimize the instrumentation scheme while satisfying criteria of financial cost and dependability. This method uses a structural model that describes qualitatively the different relations that link the physical variables. By analyzing this model, it is possible to obtain the different ways to estimate the unknown variables in function of the measurements provided by the sensors. The number of these ways may be interpreted as a fault tolerant level of the estimation possibilities. In this context, the optimization consists in finding the instrumentation scheme that satisfies the required fault tolerant level constraints with the lowest financial cost. The two main contributions of this paper are first an extension of the structural model in order to take into account different operating modes and their specific features and second a clear formalization of the optimization problem that takes into account the costs of devices and specified fault tolerant level.
