PID Controller Design for “in vitro” Exposure System at Mobile Phone Frequencies

In the recent years, the analysis of the possible dangerous biological effects of electromagnetic fields at mobile phone frequencies has become of relevant interest for the scientific community. The availability of a controlled exposure system may help in performing meaningful experiments. To this aim, a suitable PID control is designed starting from a mathematical model of the exposure system. Both the structure and the parameters of the proposed model are derived directly from the experimental results. The effectiveness of the controller is also demonstrated via experimental evaluations.
