In this note, a new scheme of fault detection (FD) is proposed for linear discrete time-varying (LDTV) systems subject to l 2 -norm bounded unknown inputs. The basic idea is to find an optimal estimation of the l 2 -norm of the unknown inputs including the unknown initial state variables. This leads...
