A transfer function computational algorithm for linear control systems

The problem of computing the closed loop transfer function of a linear system represented by its block diagram or by its flow graph is of importance in CAD programs designed for the analysis of linear systems. Mason's rule (1953) is one of the available techniques to perform such calculations, but it requires searching into the graph for different paths and loops and becomes slow as system complexity increases. In this paper, a method is developed to efficiently compute the closed loop transfer function and intermediate transfer functions of a linear system.<
