Control Design of Surface Temperature Adaptive Material System WANG, Hongpeng WANG, Xiaoqun* WANG, Zhenqing DU, Shanyi (School of Materials Science and Engineering, Beijing University of Aeronautics and Astronautics, Beijing 100083, China) Abstract In the industrial field a device's local surface temperature needs to follow the temperature of an outside specific object. According to this requirement a Surface Temperature Adaptive Material System was developed where the temperature control system based on TEC (thermoelectric cooler) was carefully designed. Firstly the principle and structure of the control system were introduced. Then the hardware design and temperature control algorithm were presented, and experiments were designed to verify the function of the system. Finally the working surface of a TEC device was connected to the surface of alloy material to check the performance of the system. The experimental results showed that the control system can be used in the surface temperature adaptive material system.
