Adaptive Temperature Control System for LED Array Systems

In this paper, an adaptive temperature control system for plant cultivation is proposed. The proposed method analyzes the internal temperature of red and blue LED arrays and determines the optimal fan speed for various temperature conditions. The adaptive control system is then implemented based on the analyzed data. Hence, the proposed system can better reduce the fan control power and noise than the conventional method. In the experimental results, the error between the simulation model and real system was at most 2.96%. The proposed method reduced the power consumption to 60% that of the conventional system when the target temperature was 38 °C.
