Abstract
Plasma medicine hinges on local generation and delivery of a variety of
therapeutic agents including electric fields, reactive chemical species, and thermal effects. With
an increasing number of clinically approved atmospheric-pressure plasma devices, there is growing
evidence for the effectiveness of plasma medicine in alternative and complementary therapies such
as reduction of head and neck cancer and accelerated healing of chronic wounds. However, safe and
effective operation of hand-held atmospheric-pressure plasma devices is highly sensitive to the
intrinsic variability of plasma characteristics as well as to exogenous disturbances such as
variations in the physical and chemical properties of a target substrate. Key challenges in
feedback control of these plasma devices arise from the need to: (i) handle the nonlinear,
multivariable nature of plasma dynamics, (ii) retain the system operation in a constrained region
for safe and reliable operation, and (iii) realize multiple (possibly conflicting) plasma dose
delivery objectives. In this talk, we will demonstrate the importance of using predictive control
strategies for safe, reproducible, and therapeutically effective application of
atmospheric-pressure plasma jets for thermal dose delivery in plasma medicine.
