Entry requirements

120 credits including 60 credits in science/engineering, whereof 20 credits in mathematics, and one of the courses Automatic Control I or Introduction to Computer Control Systems. Proficiency in English equivalent to the Swedish upper secondary course English 6.

Learning outcomes

The main goal of the course is to introduce the students to safety and security aspects of modern control systems arising due to their digital and networked implementation. The main course body consists of basic concepts, approaches to and methods of modeling, analysis, and detection of faults and attacks in control systems.

On completion of the course, the student should be able to:

• explain the basic principles of safety and security in safety- and mission-critical control systems;
• explain the notion of risk, and describe the main parts of risk management through system design;
• evaluate control performance under different fault models;
• model and analyze the stability and performance of digital control and control over communication networks;
• design and evaluate observer-based fault detection filters for additive and multiplicative faults;
• analyse the detectability limitations of fault detection filters for specific classes of fault and cyber-attacks;
• motivate what security mechanisms are appropriate for different classes of cyber-attacks.
• evaluate the risk of different threat scenarios, and the effectiveness of safety and security mechanisms, in a real process.

Content

The main topics covered in the course are:

• Safety and security in networked control systems.
• Control performance monitoring and control under fault.
• Fault detection and isolation.
• Cyber-attacks and security mechanisms in control systems. 

Course content:

Mathematical description of linear systems in continuous and discrete time in the presence of communication networks, faults, and attacks. Networked control systems. Sampled-data systems. Control performance monitoring. Fault detection and isolation though model-based and data-driven methods. Cyber-security in control systems and typical attack examples and scenarios. Safety and security risk management. Security mechanisms.

Instruction

Lectures, exercise sessions, homework and lab assignments, and a small project assignment.

Assessment

Assignments, laboratory work and mini project.

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
