Інформаційно-вимірювальна система для автоматичного контролю параметрів роторних систем

Abstract

The dissertation is devoted to development and research of information-measuring system for the automatic control of parameters rotor systems, which capable to provide the raised level of reliability of acceptance of the true decision. The method of measurement of frequency of rotation of a shaft by means of vibrating parameters is developed and the model of system of the automatic control difference rotations rotor systems on the basis of which is created is developed adaptive algorithm of the automatic control of parameters rotor systems which allows to raise accuracy of synchronization of frequencies rotation in 1,5-2 times. Methods of the automatic control of mechanical and vibrating parameters which complex use allows to lower probabilities of acceptance of the erroneous decision are developed. On the basis of the developed methods hardware-software realization of information-measuring system for the automatic control of parameters rotor systems is constructed. It is analysed dynamic metrological characteristics akselerometr and static metrological characteristics of measuring channels. Mistakes of the first both second sort and reliability acceptance of the true decision on the basis of which the general reliability of the automatic control which makes 0,98 is estimated are found. Experimental researches which confirm adequacy of the developed theory and efficiency of the offered methods are lead.
