This paper proposes an interval observer design for a large class of uncertain LTI systems. The proposed methodology estimates simultaneously the upper and lower bounds of unmeasurable states and unknown inputs. The initial model is transformed into a singular model representation without unknown input reducing the conservatism related to the propagation of uncertainties in set membership approach. An example is proposed to demonstrate the efficiency of the method.
