摘要
对于广义系统的能控性和能观性的研究已经取得了很多成果,但对于正广义系统的研究,目前还处于起步阶段,需要进一步的研究.本文研究了一类正广义系统,通过Drazin逆给出了判别系统能控性和能观性的充分条件,并通过例子验证了本文结论的有效性.
Recent research on controllability and observability of descrippor systems have been made. But very little is known about positive descriptor systems up to now,there are still many problems need further research.Positive descriptor systems, a special class of the descriptor systems, is considered.The sufficient condition of controllability and observability are given by Drazin inverse.An example verifies the conclusion.
