Learning outcome

Knowledge: The candidate can explain

• the purpose of introducing control loops.
• functioning and purpose with each component in a control loop.
• correspondence between the presented representational forms for dynamic systems.
• the terms steady-state and dynamic error, response time and stability, and how they can be specified.
• how the choice of controller influences steady-state deviation, response time and stability.

Skills: The candidate can

• carry out experimental and mathematical modelling of simple processes.
• draw block diagrams of simple processes.
• reduce block diagrams.
• tune controllers using the lectured methods.
