In this thesis, three coils are controlled and given a sinusoidal magnetic field in order to open and close a magneto-active polymer actuator which can work as a peristaltic pump. The thesis is divided in three parts: The first one contains a Codesys program and an electrical circuit where Analog Output Wago Module 750 556 is used. The software program has as an output a sinusoidal wave which has to be amplified. This is done in the electrical circuit. The second part is also the design of a Codesys circuit and an electrical circuit using the Digital Output 750 502 module in order to control the three magnet coils. The Codesys Output has as an output a pulsed signal and using the pulse width technique the magnetic field can be controlled. The last part is the tests of different pulsed signal Codesys programs. The frequency and the signal pulsed are not the same between the software programs. The behaviour of the peristaltic pump is analysed and compared to different programs. Conclusions are extracted from the results of the tests and from the development of the electrical circuits and software programs.
