Examiner:
Professor
Bengt Lennartson
Eligibility:
For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.
Aim
The course will give knowledge of and proficiencies in:
* Construction of dynamic models for technical systems.
* Possibilities and limitations of feedback systems.
* Fundamental principles for analysis and design of control systems, with focus on design in the frequency domain.
* Usage of typical control components, such as PID-controllers.
Content
Introduction: Examples of control problems, dynamic systems, open and closed loop control, compensation of disturbances, servo functions, treatment of parameter variations.
Dynamic models: Transfer functions, block diagrams, transient and frequency analysis, Bode plots. Principles of construction of dynamic models for technical systems. Special attention is paid to similarities between systems from completely different technical areas. State models, linearisation and simulation.
Analysis of feedback systems: Stability, the Nyquist criterion, stability margins, sensitivity and robustness with respect to parameter uncertainties and non-modelled dynamics. Performance and accuracy, transient and stationary performances, specification in the time and frequency domains.
Design of control systems: Fundamental principles of controller design, possibilities and limitations depending on interference between different frequency areas. Design of PI and PID controllers, different control structures such as one and two degrees of freedom, cascade and feedforward. Design of controllers based on state space models, controllability and observability, state feedback.
Implementation: Brief theory of discrete-time systems, digital implementation based on analogue design, bump-less transfer when starting and handling control signal limitations.
Laboratory session: Tuning of a PID controller for a tank process.
Assignments: Assignments that are solved by mainly using Matlab.
Organisation
Lectures, group exercises, laboratory session in the department lab, and mandatory home assignments solved in groups of two.
