Syfte

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.

Mål

Kunskap och förståelse

För godkänd kurs skall doktoranden

• 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.

Färdighet och förmåga

För godkänd kurs skall doktoranden

• 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.

Värderingsförmåga och förhållningssätt

För godkänd kurs skall doktoranden

• 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.
