Control Engineering

Introduction to practical control engineering. Representation of dynamic systems with ordinary differential equations. Linearization. Laplace transform and transfer functions. Block diagrams. Frequency analysis. Experimental and mathematical modelling of physical processes. Stability theory and stability investigations. Tuning of PID-controllers based on analyses both in the time and frequency domain. Practical limitations and alternative control structures. Realization of control algorithms.

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.
• calculate how disturbances influence both the controlled and uncontrolled system.
• analyze stability, and quantify stability margin.
• make use of modern computer tools within all mentioned areas.
