My question for the Net is: has anyone out there had the gumption and patience to create any design tool(s) of the sort that would be of use to somebody studying and designing digital and analogue controllers? More specifically, programs to convert to and from the Laplace and Z domains; programs to plot Root-Loci, Poles-and-Zeros, Time Responses, or Bode/Phase and Nyquist plots; programs to calculate the coefficients of various filters; anything perhaps less sophisticated but related to these? A few of these tools I do not intend to be without for very long but I would really love to spend my time more efficiently than in reinventing and coding the wheel. -- Peter Hansen, Systems Design Engineering, University of Waterloo silent@watale.uwaterloo.edu

In response to you question regarding control theory, I have a number of routines available, including 1. Bode Plot 2. Optimal Pole Assignment for Linear, Time-Invarient Systems 3. Hamiltonian Matrix 4. Working on sensitivity routines. 5. Working on time response. 6. Working on non-linear optimal control solutions. In order to facilitate timely solutions, does anyone know how to speed up the HP-48SX. I know it can be done on the HP-28S. James Walters Evenings 619-375-4465

This would allow conventional "straight" line bode graphs to be plotted (Used in circuit analaysis classes).. The one I have only does non-log w scale... The vertical scale (Magnitude or Phase) can be in LOG or normal scale but the horizontal axis (w) can't be changed... Could you please post your programs to the net?
