Routh-Hurwitz Stability Criterion with GUI MATLAB V3.3

This GUI Solve Routh-Hurwitz Stability Criterion

Features:

1-Calculate Exactly & Display Table Of Routh Hurwitz In Listbox
Similar Project Can't Solve Accurate Routh-Hurwitz Stability Criterion
For Example This Equation [1 1 3 3 3 2 1] Have All Element And First
Element Zero Simultaneity And I Test Any Project And None Solve It

2-Determine Where First Element Or All Element Is Zero Graphically(Change Own Row Color Voluntary)
Similar Project Show This With Text And Confuse Us

3-Factor s=0 Roots
Similar Project Don't Have This Feature . This Gui Factor s=0 Roots
And Solve Routh-Hurwitz Stability Criterion

4-Display Number Of Roots
This Gui Show Number Of
4-1-Repeated Roots On jw Axis
4-2-Left Half Plane Roots
4-3-Roots On jw Axis
4-4-Right Half Plane Roots
4-5-Number Of Center Roots(s=0) That Factor From Input Equation
4-6-Number Of Repeated Center Roots(s=0) That Factor From Input Equation

5-Display Result
5-1-Unstable System
5-2-Boundary Stable System
5-3-Stable System
Note: s=0 Roots That Factor In Input Equation Affect On Result

6-Find Upper & Lower Limit Of Variable k(Gain) With Gain Finder Tools
Input Equation(Poly Only) With k Variable(For Example: [1 0 5 0 k])
And Set Start & To & Interval Value

This Show Stable & Boundary Stable & Unstable Of Each k Value
Default Colors Is:
Stable:Blue
Boundary Stable:Green
Unstable:Red
You Can Change Color Voluntary

7-Save Table Of Routh-Hurwitz
You Can Save Table Of Routh-Hurwitz In .mat Format For Future Usage

8-Color Scheme(Beautiful)
You Can Change Color Scheme Of This GUI

9-Solve Equation
You Can Obtain Roots Of Input Equation With This
Note: s=0 Roots That Factor In Input Equation Appear Here

10-Step & Impulse Response
You Can Plot Step & Impulse Response By Determine Numerator
And Denominator Of Transfer Function .
Default Numerator Is [1] And Default Denominator Is Poly
State Of Input Equation
Note: If Number Of Zeros Greater Than Poles Then Gui Give Error Message

11- Z_plane Diagram
You Can See Z_plane(Place Of Zeros & Poles) In The Figure

12-Root Locus & Nyquist & Bode Diagram & Singular Value & Nichols
You Can See Above Diagram By Determine Numerator & Denominator
Of Transfer Function Be Similar To Section 9

13-Plot With LTI Viewer Of MATLAB

14-Support 2 Language
English & Farsi
