Abstract :
This paper presents a new definition of negative imaginary (NI) systems to include poles at the origin. Also, a necessary and sufficient stability conditions of positive feedback interconnection of NI systems that have poles at the origin with a strictly NI system is provided. As an application of this class of systems, an example of a train system is presented.
