Abstract:

The System Time Domain SYSTID computer program was developed for NASA by SYstems Associates, Inc. in 1971 for simulation of electronic communication systems. SYSTID is a two-phase computer program which uses z-transform digital sampling techniques and has a library of models available for use in simulations. The program was written for operation with A UNIVAC 1108 EXEC II operating system therefore, it was necessary to convert it for running under EXEC 8 at NUSC. The conversion process involved rewriting of some of the SYSTID PHASE I subroutines for compatibility with EXEC 8. The EXEC 8 runstream necessary for running SYSTID at NUSC is described. Examples of modeling with SYSTID for a simple wave generator and a second order positional servomechanism are given. These examples help to show that SYSTID can be used ful for modelling of systems operating at frequencies from nearly DC to RF while using a system block diagramsubsystem transfer function response.
