本文讨论无环向图和皮特利网描述的一类离散事件动态系统的特征值的求解方法。对事件延迟系统,给出了频域的特征矩阵M(z)的特征值求法,并由之提出一个新的求取闭环无环向图描述的离散系统特征值的方法。
This paper discusses the solution of eigenvalues for a class of discrete-time dynamic systems described in acyclic graphs and Petri nets. For the event delay system, the eigenvalue of the eigenvalue matrix M (z) in the frequency domain is given, and a new method to find the eigenvalue of the discrete system described in the closed-loop acyclic graph is proposed.
