Aim

The course gives an in-depth treatment of design of linear control systems with limitations. Special attention is given to design trade-offs and fundamental limitations, and how mathematical optimziation can be used as a design tool, both offline and online. The course covers both continuous-time and discrete-time control systems.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to translate between, and intelligently select among, different representations for continuous-time and discrete-time systems, in particular transient responses, transfer functions, and state-space descriptions.
• be able to derive properties of interconnected systems from the properties of their subsystems, and to characterize and quantify the role of the different subsystems.
• be able to formulate constraints on input signals and output signals of a control system and to relate these to conditions on the matrices that describe the system.
• be able to analyse how process characteristics put limitations on the control performance that can be achieved.

Competences and skills
For a passing grade the student must

• be able to independently formulate technical specifications based on understanding of the control system should be used and interact with the external environment.
• be able to select control design methods and model structures, and translate specifications into mathematical optimization problems to be solved online or offline.
• draw conclusions from numerical calculations about the correctness of models and specifications, and about the consequences for the interaction between the system and the environment.

Judgement and approach
For a passing grade the student must

• understand relationships and limitations when simplified models are used to describe a complex and dynamic reality
• show ability to teamwork and group collaboration at laboratories.

Examination details

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: Written exam (5 hours), three laboratory exercises, one hand-in assignment. In case of less than 5 registered students the retake exams may be given in oral form.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
