Conversion of Block Diagrams into Signal Flow Graphs
1. Why Block diagrams are converted into signal flow graphs?
This conversion is done for clear and visual representation of the system. Along with this SFGs help in path identification and feedback analysis. It also helps in easier gain calculation.
2. In what type of systems Signal flow graphs are used?
It is applicable to linear system and are not effective in non-linear systems.
3. Why SFG is used in control system?
It is used in control system because it helps in analyzing the various components of the control system. identification of paths and feedback loops and finding the overall gain.
Conversion of Block Diagrams into Signal Flow Graphs
In this article, we will discuss the method of converting the block diagram into a signal flow graph in a control system. We will first discuss about signal flow graph and its terminologies. We also discuss the construction of signal flow graphs from linear equations. We will then discuss about block diagram and its components. We will then discuss the steps for conversion and then see an example. We will discuss the Mason gain formula and its example. Later in the article, we will discuss the advantages, disadvantages, and applications of this method.
