Training program BODE-Trainer

Scope of performance

The BODE-Trainer is a program which is primarily intended for training purposes to learn the dealing with Bode diagrams of simple and composed systems and the stability analysis according to the Nyquist criterion. For that purpose any number of linear standard elements (P-, PT1-, PT2-element etc.) can be combined to a series connection and the Bode diagrams of all single elements as well as the composed system can be presented in many different forms. Furthermore characteristic values can be determined which allow a stability analysis of the corresponding closed loop.

Main features of the program:

  • Presentation of gain and phase characteristic alternatively exact or asymptotic (approximation by straight lines)
  • Presentation alternatively in one or two separate diagrams
  • Input and parameterization of single elements via comfortable dialogs and sliders
  • Adding and deleting of single elements
  • Loading and saving of systems
  • Automatic evaluation of characteristic values for stability analysis (gain crossover frequency, phase margin, gain margin, …)
  • Display of auxiliary lines for the graphical stability analysis, if desired
  • Alternatively automatic or manual scaling
  • Comfortable measurement functions
  • Saving of frequency responses for processing in other WinFACT modules
  • Printing standardized to half logarithmic DIN A4 paper, if desired
  • Line width, curve colors and grid customizable
  • Automatic saving of all settings at exiting program
  • Online help
