Abstract:A Proportional-Integral-Differential controller is a control loop mechanism, commonly
used to force a controlling parameter, e.g. temperature, to a desired value at satisfying
accuracy. It is a simple algorithm, which is easy to implement, and it is therefore widely
used to control both laboratory and industrial processes.
The aim of this project was to adopt a PID controller for the temperature stabilization of
low temperature measurements. The temperature sensor was a resistor with temperaturedependent resistivity.
In this work I analyzed the physical properties of the system under control affecting the
temperature stabilization, and investigated the logic behind choosing proper parameters for
the PID controller. I compared the experimental results with analysis of the system based
on solution of the differential equations for the system dynamics.
