Learning outcomes
|
The aim of the course is to acquaint students with the basics of the theory of automatic control and regulation. The course mainly deals with the theory of linear control of one-dimensional control circuits, description of control circuit members in continuous and discrete domain (use of Laplace and Z-transform), properties of members, basic types of industrial controllers (P, I, D and their combinations, discrete PSD version continuous PID controller), solution of control circuit stability, basic methods of control circuit synthesis.
After completing the course, you understand the basic control theory. You can derive the model of the regulated system and find out its basic characteristics (response to the input signal, frequency characteristics), create block diagram of a control circuit and derive the transfer fucntion. According to the quality requirements of the control process, you can select the correct type of controller (P, I, D and their combinations) for the given system and set the parameters of the controller correctly with regard to the quality requirements and stability of the control circuit. You have also has basic knowledge of the theory of discrete control (description of discrete control circuit, stability of discrete systems, digital PSD controllers).
