This talk will focus on the principles behind closed-loop systems in physiology. Starting with the general concept of homeostasis, we will first cover selected closed loop systems at the organ level. As illustrative examples, we will look at the control loops for temperature and ventilation. Afterwards, we will introduce categories for closed-loop controlled therapeutic devices and illustrate this with selected examples. We will then move down to the cell level and take a look at physiological closed-loop systems on that scale. Here we will discover negative as well as positive feedback loops.
Steffen Leonhardt has studied Electrical Engineering with a major in control and design at TU Darmstadt and with a major in Computer Engineering at SUNY at Buffalo, NY, USA. Furthermore, he has studied Medicine at Goethe University Frankfurt. Working on fault diagnosis for mechatronic systems, Steffen has been a research assistant at the Institute of Automatic Control (Head: Prof. Isermann) and has obtained the Dr.-Ing. degree (Ph.D.) in Control Engineering in 1995. In 2001 he obtained the Dr. med. degree (M.D.) with a thesis on automatic lung function diagnosis for infants. From 1999 to 2003, he was working in the R&D department of Dräger Medical AG & Co. KGaA, Lübeck. As a R&D manager, he has lead two R&D projects. In 2003, he was appointed full professor and head of the newly established Philips endowed Chair for Medical Information Technology at RWTH Aachen University.
