Zeros in discrete-time MIMO LTI systems and the output-zeroing problem (English)
0 references
The author gives an interpretation of invariant zeros of multi input multi output linear time invariant systems, called geometric, considering them as a triple (complex number, state zero direction, input zero direction). The interpretation of zeros in the context of the ouput-zeroing problem is given, extending the notion of a Smith invariant zero. NEWLINENEWLINENEWLINENo comparison is made with the geometric and algebraic notions of invariant zeros such as the Zero-module and the maximum \((A,B)\)-invariant submodule in Ker \(C\), which are of interest in control theory.
