Necessary conditions for positive realizability of continuous-time linear systems |
|
| Authors: | Lorenzo Farina |
| Abstract: | This paper deals with the positive realization problem. The problem is to find, from a given transfer function, a state equation in which state variables and the output take nonnegative values whenever initial states and inputs are nonnegative. Necessary conditions are investigated and a new one is given, together with some related results. |
