Investigation on a Temperature Control System Modeled after the Function of the Skin

The contraction and relaxation of muscles located below the skin play an important role to maintain a constant internal body temperature. In this paper, we propose a new temperature control system modeled after the functions of the muscles located below the skin. The most important feature of this system is that the precise control of internal temperature is achieved by the operation of flow rate allotment. Moreover, we used digital adaptive control to improve the performance and flexibility of this system. To verify the validity of this system, the experiments were carried out and it was shown that this system can control the internal temperature within the range of ±0.02°C.
