Abstract: This paper develops an Adaptive fuzzy sliding-mode control system algorithm for active heat dissipation system. In the proposed intelligent controller, The adaptive laws adjust the parameters of the fuzzy logic system on-line based on a Lyapunov function, so that the stability of the system can be guaranteed. Additionally, an error estimation mechanism is investigated to estimate the bound of the approximation error. Based on NI-PXI system, this research combined the (TEC) with a duct heater. It designed a smart control system featured by the new active heat dissipation system. It has been proved that this research proposes the ideas of the active heat dissipation adaptive fuzzy sliding-mode control system which may reach a good condition provided with correct temperature control function. To be more precisely, that can be easily adaptive to any environment. It is equipped with a good capability of tracking and searching.

Abstract: In this study, a constant temperature environment chamber with high stability is proposed. In the proposed design, the outer temperature is controlled by the air conditioner, the inner temperature is controlled by the electric current generated to control several thermoelectric cooling units. The separation design of the environment chamber from the cooling system can reduce the vibration caused by the thermoelectric cooling elements. This system adopted the Rake’s System Identification Method to obtain the system model, so that optimum PID parameters can be acquired from the simulation of Matlab Simulink. The results show that the vibration can be effectively reduced and the temperature can be controlled within the range of 20±0.007°C in the steady state.
