ANALYSIS OF DYNAMIC CHARACTERISTICS OF AN UNSTABLE CONTROL SYSTEM WITH DISTURBANCE

Abstract

The analysis and study of the dynamic characteristics of automatic control systems (ACS) is an important key task in control theory. This article is devoted to the construction of transient characteristics of an unstable system using graphoanalytic methods. The following dynamic characteristics of the system were obtained: static deviation, maximum deviation, acceleration time and overshoot.

It is convenient to build the characteristics of control objects (CO) using simulation modeling systems. The VisSim visual modeling system is used in the work, which allows automating the process of construction and analysis. The advantage of using graphoanalytic methods over analytical ones lies in their clarity and simple interpretation.

The results of the CO analysis can be used in the educational process when studying the subjects “Linear ACS”, “Nonlinear ACS”, “Sensors and signals”, “Modeling and identification of control objects”, etc
