[scilab-Users] time delay with syslin?

[Dean Parsons]

Samuel,

Thank you for the information. This code does indeed allow me to create a linear continuous time system with a time delay via a new Scilab function called "iodelay". It also creates a new Scilab datatype also called "iodelay" and also modifies the Scilab functions bode, nyquist, black, and repfreq so that they can handle this new datatype.

Unfortunately it is still not useful for my purposes because I need to convert a continuous time linear system with a time delay to a discrete time linear system --- which I was hoping to do with the Scilab function "dscr" --- however, I cannot do this because the dscr function cannot handle the new iodelay datatype. 

Could someone create an overloaded version of dscr that will handle the iodelay datatype? If so, then I believe I could achieve my purposes.

    Hello,

    I would like to know if it is possible in scilab to specify a time delay for an input signal to a continuous-time linear system such as one created with 

    sys1 = syslin('c',A,B,C,D);

    In other words, can I create a continuous time state-space model with a time delay?
  I do not know if it is convenient, but it could likely be : You may have a

  Please let us know if it is actually useful to your purpose.

  Regards
  Samuel
