Ketercapaian dan Keterkontrolan Sistem Deskriptor Diskrit Linier Positif
A positive discrete descriptor system has been widely used in modeling economics, engineering, chemistry and others. In this research, we studied the necessary conditions and sufficient conditions for a positive discrete descriptors system is achieved positive and controlled postively. In addition, it is also studied on sufficient terms and conditions which ensure that discrete systems (E,A,B)≥ 0 are null controlled. By using linear algebraic method and Inverse Drazin, this research has proved several theorems for discrete descriptors system (E,A,B)≥0 achieved positive, controlled positively and controlled null. In addition, examples are given as illustrations to reinforce the validity of the proven theorems.
