Mood disorders, which are greatly affected by stress, are at the forefront of health concerns confronting the world today. This research introduces and evaluates a framework for feedback control of stress using audio stimuli and electroencephalography sensing. We propose a control system configuration which includes calibration of stress based on brain activity in each trial via a regression model. Next, the input-output mapping between music characteristics and stress is modeled as a dynamical system, and validation results are provided that indicate that this relationship can be approximated by a linear model. Finally, we assess the outcomes of preliminary proportional control testing. Hopefully, the findings of this research can stimulate future investigation of the use of feedback control for emotion regulation that will have a positive effect on mood disorders.
