Robust Control of Thermal Dose in a System with Uncertain Biological Parameters

In this paper a new approach for controlling thermal dose, considering the uncertain biological parameters, is proposed. Firstly, ignoring uncertainties, an optimal temperature controller has been developed that used minimum amount of energy. secondly, considering uncertain biological parameters , an H∞ robust controller is designed that not only decreases the disturbance effect but also determines the admissible maximum bound of plant uncertainties which still can be stabilized by that controller.
