The subject is taught in programs
Electrical engineering 1st level
Objectives and competences
The purpose of this course is to provide the students with the basic knowledge and tools of modern linear systems theory in several domains. The students will gain knowledge on modelling, time and frequency domain analysis, state space approach, stability, controllability, and observability and illustrative aapplications of systems theory in optics and biological systems. The students will also be introduced to the computational tools for linear systems theory available in Matlab and Python.
Teaching and learning methods
The lectures provide a theoretical background on particular subjects together with presentation of simple illustrative examples. Additional examples are presented and discussed in tutorials. Practical work is being carried out within laboratory exercises, where students prepare reports for each assignment.
Expected study results
After successful completion of the course, students should be able to:
-classify linear systems and describe their basic properties,
-use systemic approach to analysis of linear electric circuits,
-analyze the properties of linear systems in time domain, frequency domain and state space,
-use linear system analysis methods for modelling and evaluation of biological and optical systems,
-use some of the existing Matlab and Python libraries for numerical analysis of linear systems.
