Problems solved by technology

Moreover, due to the complexity of the outdoor environment, the relationship between the state parameters that affect the stability of the power supply box is getting closer and closer. Only relying on a single state quantity to realize the control of the fan speed may not be able to accurately judge the state of the power supply box. , and may even cause misjudgment or misjudgment. For example, when the temperature rises, it is obviously too late to adjust the fan.

Abstract

The invention discloses a military power supply case fan rotating speed control method. A traditional PID control principle, a neural network technology, a fuzzy control technology and a predictive control technology are combined, a novel controller structure is provided, by means of a neural network fuzzy PID control method based on a linear predictive model, a case temperature is judged in advance, and a fan rotating speed can be adjusted in time, so that stable power supplying of a military power supply case is achieved; moreover, multiple kinds of state quantities are acquired for comprehensive judgement, and a power supply case state can be monitored more accurately, so that a more accurate and reliable temperature adjusting mode is provided, and the precision of a power supply case power supplying amplitude value is greatly improved.

Description

technical field [0001] The invention relates to a method for controlling the rotational speed of a fan of a military power supply case. Background technique [0002] In the traditional military power chassis design, especially in instruments and meters, the fan speed is usually fixed. Even for computers, the fan speed can only be set in the BIOS, and the temperature inside the chassis cannot be adjusted as needed. However, due to the complex outdoor environment of the military voltage chassis, various environmental factors have a great influence on the temperature inside the chassis, frequent changes in temperature or continuous overheating will affect the stability of the power supply of the power supply chassis, resulting in serious adverse consequences, so it is urgent to provide A power chassis that can adapt to multiple complex and changing environments to provide a stable power supply. As the main equipment for temperature regulation of the power supply box, the fan c...
