Universal GUI for Easy and Fast Analysis of Dynamical Systems Performance

The paper presents a systematic approach to the design of a graphical user interface (GUI) that is suitable for analysis of properties of linear dynamical systems (basic graphs like time responses to prescribed exciting signals, frequency characteristics, and numerical outputs like transfer functions coefficients, state-space form, values of system zeros and poles with optional output of the results into an Excel file). For the good readability, there are two screens - graphical and numerical one. In distinction to similar single-purpose solutions the presented GUI offers a possibility to perform the analysis user friendly and fast for a whole range of dynamical systems. The design is explained on examples from fields of multi-loop electrical circuits (based on the mesh method and the nodal analysis method) and of multi-mass translating and rotating mechanical systems. The four GUIs were unified into one file where the user chooses the kind of the system, system parameters, and impedance matrix in form of multiply tables. Based on an analogy among systems from various physical domains the user can easily modify the application for his/her needs.
