Input observability and input reconstruction
The problem of input observability and reconstruction for linear time-invariant systems is considered. Corresponding necessary and sufficient conditions which are explicit and testable are given. The approach developed for the design of schemes for input reconstruction is based on a matrix pencil decomposition form which is obtainable using numerically stable orthogonal transformations. Moreover, the relationships among input observability, system invertibility and unknown-input state observation are considered.
