Subject description

Prerequisites:

The prerequisites are in accordance with the rules at UL FS. The students are advised to regularly attend the lectures. The students must attend at least 80% of the tutorials, adequately prepare for laboratory work, and be active during the tutorials. To consolidate the knowledge presented at the lectures and tutorials, the students must complete five mandatory homework assignments. As prerequisites for this course, basic knowledge of electronics and programming (C/C++) is required.

Content (Syllabus outline):

Introduction

Mechatronic system:

Basic structure. Power subsystem. Object of control. Description of the object of control and its transfer function. Actuator elements. Power control. Load-gear-motor subsystem. Power subsystem transfer function. System analysis. Control synthesis. Static and dynamic system characteristics.

Modeling functional units:

Specifical requirements for electromotors and mechanical transmission elements in the mechatronics. The control ability. Control motor characteristics. The specifics of control. Model transfer functions for DC, AC and stepper motors. Criteria for sizing and selection.

Mechatronic system modeling and simulation:

The modeling environment. Model development and model simulation. Model verification. Selecting the system elements, integration, analysis and synthesis of the positioning and velocity system based on electromechanical functional elements. Developing a mechatronic system in a hybrid loop (hardware-in-the-loop), consisting of the model elements and real control elements. System integration through program code.

Mechatronic system synthesis and realisation: Single-axis examples of positional and velocity systems. Multi-axis examples. Harmonizing motion, interpolation.

Mechatronics in the automotive technology: Safety, economy, comfort ensuring systems. Controllers for automotive applications and communication between the systems.

Example applications of mechatronic systems: in manufacturing, in vehicles, in machine tools, in the energy industry, in process engineering, in buildings, in products for mass consumption.

Objectives and competences:

Goals:

The fundamental course goal is to provide the students with comprehensive knowledge to design, manufacture, put into service, test, operate and maintain mechatronic systems. Emphasise is placed on a systematic approach to the analysis and synthesis of mechatronic systems.

Competences:

The student learns about the structure of mechatronic systems and the characteristics of specific functional elements of the power subsystem – mechanical, electromechanical, electronic, control, software elements. They learn the steps of power subsystem analysis and synthesis. The students learn about the typical structures of electromechanical subsystems and their transfer functions. They learn in detail about the principles of system modeling and simulation, as well about the concept of developing a system in a loop consisting of model elements and real elements. The competences mastered serve as a foundation for the development of more complex mechatronic systems.

Intended learning outcomes:

Knowledge and understanding

The students attain knowledge about the structure of mechatronic systems, with an emphasis on power subsystems. They earn knowledge about the typical elements, their characteristics and selection criteria, system planning, as well as about the criteria for the selection of functional elements and their characteristics.

The students of Engineering pedagogy get acquainted with the educational technology, teaching collections and teaching aids in different secondary school programs of technical orientation, for the field of mechanical engineering.

Usage

The knowledge attained in the course is the foundation for planning, developing, building, operating and maintaining mechatronic systems.

The students are capable to deliver a class in scope of the teaching demonstrations for specialised mechanical engineering courses at a secondary school.

Reflection

Integrating the theoretical and theoretical knowledge with the skills and experience gathered at the laboratory exercises, the students will be able to:

  • recognise the problems that can be solved as mechatronic applications
  • transfer and use the mastered knowledge on similar cases in the real environment.

Transferrable skills

Systematic approach to problem solving. Systemic (cybernetic) system structuring. Understanding the interdisciplinarity in developing, building and operating modern computer-controlled technologies.
