Conclusion
Controllability and observability of uncertain linear time-invariant systems

In this article, we have progressively introduced and developed the notions of governability and observability of single-input-monosor output linear systems, with some extensions to the case of multi-input-multisor output systems, before concluding with an extension of the notion of governability to the case of uncertain linear systems.

The concepts presented were applied using MATLAB software. It should be noted, however, that alternatives (freeware) such as OCTAVE or SCILAB exist.

Finally, although we have limited ourselves here to the framework of stationary linear and linear uncertain systems, it should be noted that the notions of governability and observability can also be generalized to certain classes of time-varying
