From: amin on 22 Jan 2010 02:29 This GUI Solve Routh-Hurwitz Stability Criterion even if all element of row or first element of row is zero(0) features: 1-Calculate exactly similar project cant 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 similar project show this with text and confuse us 3-Factor s=0 roots similar project dont 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-Save table of Routh-Hurwitz you can save table of Routh-Hurwitz in .mat format for future usage 7-Color Scheme(beautiful) you can change Color Scheme of this GUI 8-Solve Equation you can obtain roots of input equation with this note: s=0 roots that factor in input equation appear here 9-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 10- Z_plane Diagram you can see Z_plane(place of zeros & Poles) in the figure 11-Root Locus & Nyquist & Bode Diagram you can see above diagram by determine numerator & denominator of transfer function be similar to section 9 12-support 2 Language English & Farsi 13-Examples this gui have 4 example for help you 14-Internal Help this gui have internal help in html format 15-user freindly everywhere you have mistake gui help you with messages ------------------------------------------------------------- for run this gui open matlab and run Routh_Horwitz.m ------------------------------------------------------------- IRAN_Khozestan_Mahshahr University Of Mahshahr only for "Mir hossein moussavi" ************************************************************ created by amin heidari email: amin_heidari66(a)yahoo.com 22/01/2010 10:42 am All Rights Reserved *********************************************************** download link : http://rapidshare.com/files/339164078/routh_hurwitz_V2.5.zip.html |
