چکیده

This paper is concerned with α– and D–negative imaginary systems. The definition of α–negative imaginary transfer functions is firstly introduced. Then, the relationship between negative imaginary and α–negative imaginary transfer functions is studied. By means of the generalized inverse, an α–negative imaginary lemma is proposed to test the α–negative imaginary property of transfer functions. Also, a necessary and sufficient condition is provided for the α–stability of interconnection of negative imaginary systems. A state-feedback controller design condition is established such that the resulting system is α– negative imaginary. Moreover, the concept of α–negative imaginary transfer functions is extended to that of D–negative imaginary transfer functions. Finally, the developed results are illustrated by numerical examples.

abstract: To understand recently established empirical p + α potentials, RGM calculations followed by inversion are made to study contributions of the d + 3 He reaction channels and deuteron distortion effects to the p + α potential. An equivalent study of the d + 3 He potential is also presented. The contributions of exchange non-locality to the absorption are simulated by including an phenome...

On non-proper negative imaginary systems

This paper studies non-proper negative imaginary systems. First, the concept of negative imaginary transfer functions thatmayhavepoles at the origin and infinity is introduced. Then, a generalized lemma is presented to provide a sufficient condition to characterize the non-proper negative imaginary properties of systems. The generalized lemma is given in terms of complex variable s in the quart...
