摘要：This paper deals with the problem of modelling continuous systems. For simulate a PID controller, we used virtual environment Matlab. The goal of this article is to give information about the topic of the basic regulators PI PD simulation and PID too. Eventually, solved issues have to bring to professionals simple overview of how to simulate fundamental regulators’ types in Matlab enviroment. In this paper is like a tool for modelling of dynamic systems applied Matlab. Matlab was developed by The Math Works Inc. This software has a wide application in various fields of science and technology. In the theory of automatic control is becoming even one of the most used software tools in the world. MATLAB just like any other simulation program means allow to express some thoughts in several ways. The advantage of Matlab is the opportunity to work with blocks of similar blocks commonly used in schemes for control technology. Dynamic systems which need to be modelled can be assembled from standard blocks. These are predefined in libraries Simulink and with using simple copying them can be applied their directly in Matlab.
