The case of finite dimentional space is also treated. However, it’s noticed that the state ideal observability can never be fulfilled within an infinite dimensional phase space in the case of scalar output. The case of bilinear discrete-time system with delays in observation is also described. To illustrate this work some examples are presented.}, type={Artykuły / Articles}, title={Ideal observability for bilinear discrete-time systems with and without delays in observation}, URL={http://www.czasopisma.pan.pl/Content/109504/PDF/ACS-2018-4-5.pdf}, doi={10.24425/acs.2018.125485}, keywords={bilinear systems, Hilbert spaces, ideal observability, observability subspace, delayed observation}, }
