labview pid temperature controller saturation

Coupled electromagnetic thermal finite element analysis simulations were used to identify the initial controller gains. A standard reference material copper wire was used as the heat source to verify the controller performance in gel phantom experiments. A proportional-integral-derivative (PID) control algorithm was designed and implemented in NI LabVIEW®. Methods: We report the development of a control system to maintain target temperature during MHT with an automatic safety shutoff feature in adherence to FDA Design Control Guidance. One of the challenges of MHT is thermal dose control and excessive heating in superficial tissues from off target eddy current heating.

Introduction: Magnetic hyperthermia therapy (MHT) is a minimally invasive adjuvant therapy capable of damaging tumors using magnetic nanoparticles exposed radiofrequency alternating magnetic fields. 4Department of Materials Science and Engineering, Whiting School of Engineering, Johns Hopkins University, Baltimore, MD, United States.3Department of Mechanical Engineering, Whiting School of Engineering, Johns Hopkins University, Baltimore, MD, United States.2Department of Mechanical Engineering, School of Science, Engineering, and Technology, The Pennsylvania State University-Harrisburg, Middletown, PA, United States.1Department of Radiation Oncology and Molecular Radiation Sciences, The Johns Hopkins University School of Medicine, Baltimore, MD, United States.Anirudh Sharma 1 †, Avesh Avinash Jangam 2 †, Julian Low Yung Shen 2, Aiman Ahmad 2, Nageshwar Arepally 2, Hayden Carlton 1, Robert Ivkov 1,3,4* ‡ and Anilchandra Attaluri 2 ‡
