Academic year 2018/2019
Supervisor: doc. Ing. Vladislav Singule, CSc.  
Supervising institute: ÚVSSR all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The aim of the subject is to provide students with the information on the current status and possibilities provided by the electric drives engineering for application in production machines and equipment. The task of the subject is to reach basic knowledge on such a level, so as the students are able to apply the above stated equipment and their components in their profession and to get orientation in the wide market offer of individual producers.
Learning outcomes and competences:
The subject of Electrical Servodrives enables students to acquire knowledge needed for the design and optimal setting of production machines and equipment drives in compliance with technical documentation of the drives producer of, control systems and other necessary components. Students will also gain practical skills needed for servicing and diagnostics of simple faults of electric servomechanisms.
Prerequisites:
Fundamentals of dynamics mechanisms.
Fundamentals of theory of linear control systems.
Fundamental of sensors position.
Velocity and current characteristics.
Mathematical models of electrical machines.
Course contents:
The subject provides students with the knowledge of basic problems of electric servodrives and their role in driving production machines and equipment. It concerns with defining basic requirements regarding static and dynamic characteristics of servomechanisms, explaning principles of activities of the most important components of electric servo mechanisms, methodology of the design of the most frequently used feedback circuits (position loop, speed feedback, current feedback, position servomechanism with subordinated current and speed loop, dynamic submission of position loop, communication between numeric control system and machine drives), and the description of the interaction with the inertial load at servomechanisms.
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline.
According to the possibility of teaching can be organized lectures for students by practitioners and excursions to companies focused on activities related to the course content.
Assesment methods and criteria linked to learning outcomes:
The examination is combined, consists of an oral and a written part.
Controlled participation in lessons:
The subject contains only lectures. Missed lectures are not compensated.
