Abstract
The most interesting characteristic of a MATLAB package is the very effective means of drawing up specialized models – a Simulink package. By means of a Simulink package there is an opportunity to carry out research of behavior of dynamic linear and nonlinear systems. There is an opportunity to carry out the characteristics systems input in the dialogue mode. At models creation the Drag-and-Drop technology is used. As a rule, the models used in practice have hierarchical structure, thus the hierarchy levels total isn't limited. At models creation and the subsequent modeling of physical processes there is an opportunity to trace intermediate conditions of system by means of the special blocks entering into Simulink library. In case of the own blocks development the Simulink library can be added by the user. When forming the dynamic system flowchart one or several blocks sources generating signals, and also one or several blocks receivers which, actually, and allow to receive information on a system condi-tion have to be switched on. The fast obtaining possibility of the graphic information on changes of the modelled system for a certain period is one of important advantages of pro-cesses modeling in a Simulink package It is also possible to note ample opportunities for work with signals, for example, for calculation and design of filters, including creation of pulse, frequency and transitional characteristics, the filters parameters estimates according to the measured data of input and output sequences. In this work the some creation stages of dynam-ic system by means of block charts with use of a Simulink package are described.
