    • A temperature controlling method and apparatus for a refrigerator by controlling the velocity of a rotary blade are provided. In the temperature controlling method, a fuzzy model for inferring an equilibrium velocity corresponding to the rotation velocity of the rotary blade, required for the temperature equilibrium within a refrigeration compartment, is constituted and then the fuzzy inference is performed based on the fuzzy model using the change in temperature measured at a predetermined number of portions within the refrigeration compartment to calculate the equilibrium velocity, thereby controlling the rotation velocity of the rotary blade according to the calculated equilibrium velocity. Accordingly, temperatures of each portion are accurately inferred from the fuzzy model using the values of temperature changes sensed by only a small number of temperature sensors and then the rotation velocity of the rotary blade is appropriately controlled according to the inferred positions into which cool air is to be discharged. As a result, the cool air is appropriately discharged into each portion according to the distance between the rotary blade and a target position, so that the optimal temperature equilibrium is obtained in the refrigeration compartment.
    • 提供了一种通过控制旋转刀片的速度的用于冰箱的温度控制方法和装置。 在温度控制方法中,构成用于推断与冷藏室内的温度平衡所需的旋转叶片的旋转速度对应的平衡速度的模糊模型,然后基于使用模糊模型的模糊模型进行模糊推理 根据计算的平衡速度来控制旋转叶片的旋转速度,由此在冷藏室内的预定数量的部分测量的温度变化来计算平衡速度。 因此,使用仅由少量温度传感器感测到的温度变化值,从模糊模型精确地推断出各部分的温度,然后根据冷空气所推断的位置适当地控制旋转叶片的旋转速度 出院 结果,根据旋转叶片和目标位置之间的距离,将冷空气适当地排放到每个部分中,使得在冷藏室中获得最佳温度平衡。
