Aim:
The course shall give understanding of dynamic systems and knowledge about the basic methods to analyse and design feedback control system. After completing the course the student should be able to
- understand and apply basic concepts in the area of automatic control
- transform mathematical models of dynamic linear systems between input-output form , transfer function form and state space form.
- formulate system performance in terms of rise time, oscillations, steady-state values, controllability and observability
- demonstrate how the system performance can be determined by the poles of the transfer function
- perform block diagram calculation in order to express qualitatively the effect of design parameters on the performance of the control system
- understand how frequency domain methods as Bode diagram and Nyquist diagram, can be used to design controller in terms of lead-lag filters in order to obtain desired system performance
- perform stability analysis of feedback control systems using methods such as root locus, Nyquist diagram and bode diagram
- understand and use the concept of state
- understand the basic properties of the observer and how it can be used in dimensioning feedback systems with state feedback
- understand how a high-level language as MATLAB is used for analysis and design of feedback systems
- understand how to implement control systems with the help of high-level programming (Simulink) in a laboratory environment
- be theoretically prepared to continue studies and to work in areas related to automatic control
