Abstract

The present invention provides a fan speed control method and system by introducing a power algorithm. By introducing a power algorithm, the present invention adopts an incremental PID control algorithm to calculate the fan speed when the server is running under constant pressure. When suddenly pressurized, use the power change to calculate the fan speed increment, add and sum the fan speed increment calculated by the PID control algorithm, and output the total fan speed increment, so as to avoid the fan relying on PID. The lag startup caused by regulation avoids the hidden danger of server security caused by temperature overshoot, effectively reduces the maximum speed of the fan, and realizes energy saving and noise reduction of the system.

Description

technical field [0001] The invention relates to the technical field of server heat dissipation, in particular to a fan speed control method and system incorporating a power algorithm. Background technique [0002] Most of the existing server product control strategies use the temperature PID control method. The PID control method is a very energy-saving control method. It effectively controls the fan speed and saves fan power consumption. It has also been very good in the data center room. application. The method is to control the chip temperature close to the chip T jmax When the temperature is high, the fan is allowed to gradually increase the speed, and finally the chip temperature is stabilized at T sp , the relationship between the two is T sp =T jmax -10. [0003] However, the biggest problem with the PID control algorithm is that T sp Usually with T jmax There is only a margin of 10C. When the power consumption of the chip increases very rapidly, the fan cannot...
