About
About the course
Course content
- First-principle modelling of physical-chemical-biological processes.
- Transcription into the state-space and linearisation yielding the classical {A,B,C,D} representation: the Linear Time-Invariant System.
- Laplace transform and transfer function matrix. Graphical representation as block diagrams and frequency plots with a focus on Bode plots.
- Stability for LTI systems: eigenvalue / pole criterion, Nyquist and Routh criterion.
- Simple graphical process identification of first-order plus dead-time systems.
- Model simplification starting with higher-order transfer functions.
- SISO pole-placement design (direct synthesis, IMC) yielding variations of PID controllers.
- On-Off control.
- Introduction to computer-controlled systems
- Discrete version of PID with filter and anti-windup.
- Aliasing and filtering.
- Advanced subjects: selection of observability and controllability, similarity transformation, MIMO-systems relative gain array, decoupling, model-predictive control and supervisory control.
Learning outcome
At the end of the course the students should:
- Know the fundamentals of modelling and linearization of dynamic processes.
- Know basic control theory.
- Understand the power and limitations of the feedback principle.
- Understand how instability can occur in dynamic systems.
- Know how to develop simple dynamic process models.
- Know how to tune PID controllers.
Learning methods and activities

Compulsory assignments
- Exercises
Further on evaluation
Portfolio assessment is the basis for the grade in the course. The portfolio includes a final written exam 60%, midterm examination 20% and compulsory exercises and lab-work 20%. The results for the parts are given in %-scores, while the entire portfolio is assigned a letter grade.
If there is a re-sit examination, the examination form may be changed from written to oral.
For a re-take of an examination, all assessments during the course must be re-taken.
Recommended previous knowledge
Basic physics and process technology including differential equations.
