Active vibration reduction control method and device for military computer applications

Abstract

The invention discloses an active vibration reduction control method and device for military computer applications, wherein the method includes: extracting the frequency point value for vibration reduction from the vibration signal generated by the excitation after low-pass filter preprocessing; Pass the frequency point value to the vibration effect estimator and the adaptive controller respectively, so as to estimate the vibration signal generated by the active control force of the actuator and the parameters of the control channel in the adaptive controller; use the parameters of the control channel to update The weight of the multi-actuator adaptive control algorithm, and through the updated algorithm, the active control force signal that needs to be applied by each vibration active controller applied by the military computer is obtained, and the driver drives the actuator to generate the active control force signal according to the required active control force signal. Control force to counteract the exciting force generated by external stimuli. The method is an intelligent vibration reduction algorithm suitable for the vibration environment of military computers used by the navy, army and air force, and realizes active vibration control when the frequency of the vibration source changes at a high frequency, and is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of military computer applications, in particular to an active vibration reduction control method and device for military computer applications. Background technique [0002] In order to meet the needs of applications with harsh working environments such as vehicle-mounted, ship-mounted, and airborne, various factors that affect the performance of military computers, such as electromagnetic compatibility, vibration and shock resistance, high and low temperature, and three-proof (anti-corrosion, mildew, and anti-salt spray) and other reinforcement measures. [0003] Among them, anti-vibration and shock technology is an important content of military computer reinforcement technology. For example, in mechanical environmental conditions: vibration, shock, swing and vibration, etc., vibration is the most harmful. [0004] In related technologies, the reinforcement measures taken are usually: [0005] (a) When de...

Problems solved by technology

[0010] The low-frequency vibration isolation effect is not ideal, especially the variable damping semi-active control vibration reduction system has problems such as resonance amplification in some cases, which puts forward higher anti-vibration requirements for military computers, which limits the general application of military computers. Conducive to the development of informatization and intelligence in the military field, it needs to be solved urgently
