Dynamical systems

Summary

Provides the students with basic notions and tools for the analysis of dynamic systems. Shows them how to develop mathematical models of dynamic systems and perform analysis in time and frequency domains.

Content

Keywords

Mathematical modeling, transfer function, time and frequency domain analysis

Learning Prerequisites

Required courses

• Analysis I-III
• General Physics I and II

Learning Outcomes

By the end of the course, the student must be able to:

• Represent a physical process as a system with its inputs, outputs, and disturbances, A1
• Analyze a linear dynamical system (both time and frequency response), A3
• Represent a system by a transfer function and by a linear or nonlinear state-space model, A4
• Construct a linear model of a nonlinear system, A2

Transversal skills

• Manage priorities.
• Assess one's own level of skill acquisition, and plan their on-going learning goals.
• Access and evaluate appropriate sources of information.
• Use both general and domain specific IT resources and tools
• Plan and carry out activities in a way which makes optimal use of available time and other resources.
