The Definition and Explanation of the Parameters of Mason Gain Formula in Block Diagram

Xiuli Li

Abstract

In control theory,Mason gain Formula is an effective method in finding the solution of signal flow graph.However,in finding the solution of transfer function of block diagram,Mason Gain Formula can only be used after translating block diagram into signal flow graph.Relation of signal flow graph and block diagram is analyzed.The parameters of Mason Gain Formula in block diagram are defined and explained.The concept of no touch is defined in block diagram.The expression,by which Mason Gain Formula can directly be used in finding the solution of transfer function of block diagram,is provided.
