This thesis focuses on the mathematical modeling and control of peristaltic pumps. Peristaltic pumps possess the unique property of pumping liquid without it coming into contact with the pumping mechanism, thereby preventing any contamination. The main tasks of this thesis were to research the properties of peristaltic pumps, design a simplified mathematical model, and implement a chosen control algorithm using this model. The designed algorithm was then implemented on a physical system based on an STM32 embedded system. The functionality of the algorithm was verified on this setup, and the control results were subsequently compared with the mathematical model. What makes this application more challenging is the presence of several nonlinearities in the system, which need to be modeled and taken into account during the control algorithm design. A PI and an I-PD controller were chosen for the model control, while their discrete equivalents were used for the physical system. These control algorithms proved to be an effective method for controlling peristaltic pumps.
