Abstract: A new lemma is proposed to determine the negative imaginary (NI) properties of time-delay systems of retarded and neutral types. The lemma is employed for stability analysis in the context of positive feedback interconnection ...

Abstract: The operable frequency range of the delayed resonators (DR) is known to be narrow due to stability issues. This study presents a novel approach for DR design with a combined feedback strategy that consists of a delayed ...

Abstract: This paper deals with motion modeling of a 5-axis industrial Delta robot. The robot has extra rotational two degrees-of-freedom (DoF) realized with a wrist arm driven through two co-axial telescopic shafts as compared to ...
