ABSTRACT In this paper, authors propose a new design of an unknown input observer, in discrete time-domain, for a class of bilinear singular systems. In this contribution, a variable delay is considered on the state vector and a constant one is represented in both known input vector and bilinear form present in the system dynamic equation. Authors propose to apply the Lyapunov Krasovskii stability theory to compute the observer gain independently from the unknown input. Then, an unbiasedness dynamic of the observer is given to reconstruct both a state functional and a part of the unknown input. A numerical example is presented to prove the effectiveness of the proposed approach. |
