Hurwitz

Routh-Hurwitz stability criterion identifies the conditions when the poles of a polynomial cross into the righthand half plane and hence would be considered as unstable in control engineering. Platforms: Matlab

Given the coefficients of the characteristic polynomial the Routh-Hurwitz array is created and printed. Additionally, this method shows some results from the array relating to the stability of the system. Platforms: Matlab

There are 5 M-files : Routh_Gui.m, OnOk.m, routh.m, disp_result.m, funct.m. And Routh_Gui.m is used for creating the interface(using uicontrol,uipanel), OnOk.m is the callback function of pushbutton 'OK'. Based on the code written by Rivera-Santos, Edmundo J. , routh.m is modified a little to... Platforms: Matlab

The program produces Routh table and concludes upon the stability of the system.In the case of marginal stability,the exact roots are also shown,where the locus of roots will intersect the imaginary axis. Platforms: Matlab

RA=ROUTH(R,EPSILON) returns the symbolic Routh array RA for polynomial. The following special cases are considered:1) If the first element of a row becomes zero OR2) If one encounters a row full of zeros.>>syms ep>>a=routh([1 1 2 2 3 5],ep)The above given case is for encountering a zero in the...
