Unknown input decoupling and estimation in observer design for Boolean control networks

摘要

In this paper, we investigate unknown input observer design for Boolean control networks (BCNs) by applying the semi-tensor product. We introduce BCNs with unknown inputs, which can be used for modeling disturbances or noise in the system. After that, a necessary and sufficient condition for unknown input decouplability is given. Then an approach is proposed for the design of unknown input observer, which can provide the correct state estimate unaffected by the unknown inputs. Based on the proposed observer, unknown inputs can be further estimated. Finally, examples are given to illustrate the proposed approach.
