Further Remarks on Additional Dynamics in Various Model Transformations of Linear Delay Systems

This note focuses on the analysis of conservatism introduced due to some model transformations used in the control literature. This work is an extension of a previous paper by the ,same authors on additional dynamics. The additional dynamics of the second order and parameterized model transformations are examined. The neutral model transformation introduces additional constraints for stability, which can be analyzed in a very similar manner to additional dynamics. Index Terms--Delay, model transformation, stability.
