Practical Local Identifiability of Parameters of Linear Dynamic System

摘要

The problem of the practical local n- and l-identifiability of a scalar parameter of a linear dynamic system is considered. It is shown that this problem can be solved successfully by the frequency methods of analysis. The identifiability conditions are obtained in the form of simple expressions. The applicability of the n-and l-identifiability conditions developed is illustrated by an example of identification of airplane aerodynamic parameters in flight tests.
