In a variety of practical engineering systems, i.e. aerospace, mechanical systems, railway vehicle systems, for a given requirement the range of possible locations for sensors is usually known, with the practical engineering issue of optimizing their location. Input-Output selection/placement for control systems has been widely researched in particular under fault-free conditions. In this paper we discuss on the feasibility of an (output) sensor selection scheme in a closed-loop framework based on both control performance and fault detectability metrics. The selection of sensors is based upon both closed-loop control and fault detection objectives by solving a mixed H−/H∞ optimization problem for each group of sensors available via Linear Matrix Inequalities (LMI). The efficacy of the scheme is illustrated via a numerical example.
