System Dynamics

Base Knowledge

Laplace transforms

Teaching Methodologies

The classes have two components: expository and expository practice. Extensive tutorial time is offered to the
students to support their study and preparation for the exams.

Learning Results

The main goals are:
1. Simulation and control of food industry processes – the basic concepts needed to model the dynamic
behavior of representative processes in food industry are taught, preparing the student for the following
semester course Processes Automatic Control.
2. Advanced knowledge in food technology – the course aims at providing a general understanding of several
processes which are common in the food industry.

Program

1. Basic concepts for mathematical modelling of processes which are common in food industry.
2. Discussion of food processing case-studies.
3. The transfer function: development of the transfer function of a process; properties of transfer function
models; linearization of non-linear models.
4. Dynamic behavior of first-order systems: development of transfer functions of representative processes in
food industry; properties and parameters of transfer function models; transient responses to step, ramp,
impulse and sinusoidal inputs; response to an arbitrary input.
5. Dynamic behavior of second-order systems: development of transfer functions of representative processes
in food industry; properties and parameters of transfer function models; transient responses to step, ramp,
impulse and sinusoidal inputs; response to an arbitrary input.
6. Dynamic behavior of higher order systems. First-order systems in series. Pure time delay.
