ELFT2400 Control Systems Course description

The course provides basic knowledge and an introduction to control systems

Language of instruction: Norwegian

Builds on ELI2300 Dynamic Systems

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills, and general competence:

Knowledge

After completing the course the student has basic knowledge in control systems, including:

• Linearization of nonlinear dynamic model to obtain linear differential equations
• Converting linearized differential equation models to state-space and transfer function representations
• Frequency response analysis for first and second order systems
• Design of feedback controllers for first and second order systems, including time-delays, in frequency domain
• Evaluation of observability, controllability, stability and performance of feedback control systems using the state-space model
• Basic principles of numerical simulation to evaluate controller performance
• Design of low pass filters, high pass filters and lead-lag compensator
• Design of feedforward controllers and cascade controllers
• Design of multiple PID-loops for multivariable systems
• Basic principles of state estimation and observers

Skills

The student is can:

• Apply frequency analysis of open-loop and closed loop systems using Bode plots
• Apply numerical analysis of feedback control systems for observability, controllability stability, and controller performance
• Apply frequency-based tuning methods for PID controllers using phase and gain margin in a Bode plot.
• Design and implement feedback control strategies for first and second order systems with periodic inputs in a numerical simulation tool
• Apply frequency-based tuning of low-pass and high pass filters, lead-lag compensators
• Tune and test of different PID-based control structures in numerical simulation environment.
• Evaluate performance of control strategies in a numerical simulation tool

General competence

The student:

• Can design and analyze control strategies for linearized systems.
• Can test and evaluate the controller performance in both simulated and laboratory environments.
• Can communicate safety, environmental and economic aspects of feedback control strategies to engineers and general public.

• Linearization of nonlinear systems
• State-space models
• Frequency response
• Design and tuning of feedback control systems in the frequency domain
• Observability, controllability, stability and performance of feedback control systems
• Numerical simulation
• Low-pass filters, high-pass filters and lead-lag compensators
• Feedforward and cascade controllers
• Feedback loops in multivariable systems
• State estimation

Lectures, exercises and laboratory assignments.

The following coursework is a part of the portfolio and therefore needs to be approved to pass the exam:

• 4 laboratory exercises in groups of 2-3 students
• 4 assignments given during the semester

The exam is a portfolio exam consisting of the following:

• Results of four assignments given out during the semester
• Reports from four lab exercises
• Project report prepared in groups of 2-4 students. The report should be approximately 20-30 pages, including table of content and reference list
• Poster presentation of the project (15minutes)

Each student's work will be assessed together as a portfolio with one individual grade at the end of the semester.

The exam may be appealed. Upon appeal, the written work will be reassessed, and the student must complete a new oral presentation/exam.

In the case of a group examination, the right to appeal is individual. This means that each group member may only submit an appeal on their own behalf. A student who submits an appeal must complete the oral presentation individually. Failure to attend will result in the grade "did not attend" for the entire course.

In the event of a resit or rescheduled exam, an oral examination may be used instead. In case an oral exam is used, the examination result cannot be appealed.

All.

Grade scale A-F.

Two internal examiners. The course may be selected for grading by external examiners.
