Signal Flow Graph Web Simulator

GUI for generating and solving SFGs
Stability test using Routh Hurwitz criteria

We’ve been asked to design and implement a GUI application that supports the drawing of signal flow graphs with all of its components (nodes, branches, gains).
The application should be able to calculate and find all of the following from the graphical representation of the SFG:
- All the forward paths
- All the individual loops
- All combinations of n-non touching loops.
- All values of Δ, Δi - where i is represents the forward path number -
- The overall transfer function.
The application should provide the user with the capability of inserting the characteristic equation of the system and using it, the following should be calculated:
- Declaring whether the system - whose characteristic equation had been inserted - is stable or not.
- If the system being checked is not stable, the number of poles that do exist in the RHS of the s-plane should be calculated.

Introduction

This lab was developed as a part of the academic course CSE 241: Control Systems that is being studied on the 6th semester (spring 2023) in the department of Computer and Systems Engieering, Alexandria University. *As an application on the SFGs that had been studied in the course, we were required to implement a GUI simulator for it.
