Some of the functions in Control System Professional, particularly, the frequency response analysis functions, take TransferFunction objects that do not need to be based on rational polynomials, so a part of analysis of systems with time delays can be done directly. For other purposes, the linear time-invariant (LTI) approximation must be constructed first. For example, the StateSpace object takes the option Delay that allows to find the discrete-time LTI approximation of analog plant with pure time delay in the state-space form. Also, one can use the rational polynomial approximations (e.g., the Pade approximation) from the standard Mathematica packages and then apply all other analysis and design methods available in Control System Professional. Several examples can be found off the link "Downloadable Examples on MathSource" on the Control System Professional's home page (http://www.wolfram.com/applications/control), particularly, in Chapters 3, 5, and 11. Leaving it to others to comment on the second part of the post. Igor -- Igor Bakshee WRI, Applications Development Howard R.
