An Interactive Application for the Analysis of Continuous Systems

This paper presents an interactive application developed for the analysis of continuous systems that are used in many different areas of modern technology. For this reason, their analysis is crucial both for investigating the performance of systems and for synthesizing corrective algorithms to ensure their stability. The main goal of the developed application is to set up and automatically analyze continuous systems by applying an interactive approach. The application is implemented with a convenient interactive user interface, implemented in the Scilab programming environment and is particularly suitable for teaching students. It is programmed so that the continuous system can be defined by one of the two main mathematical descriptions _ transfer function and zero-pole gain model. Functions have been implemented to obtain the basic time (step response and impulse response) and frequency characteristics for a system (amplitude-phase-frequency response and logarithmic amplitude and phase frequency response), pole-zero map, as well as automatic analysis, including determining the type of system - stable, critically stable or unstable; in the case of a stable system _ its type according to the transient characteristic; parameters of the transient process in a stable system and of oscillations in a critically stable system. Tests have been made with many different system input parameters set in the two implemented ways, and the application shows stable operation.
