SELECTION OF GAS GENERATOR PARAMETERS FOR HYDROGEN STORAGE AND SUPPLY SYSTEM FOR CONTROL OF ITS TECHNICAL CONDITION
View through CrossRef
It is shown that the basis for the selection of parameters of the gas generator of the hydrogen storage and
supply system when monitoring its technical condition is the Mikhailov equation. The frequency and amplitude of
the pressure self-oscillations in the gas generator cavity are used as the monitored parameters. Expressions for
these parameters are obtained and recommendations are given regarding the determination of express estimates of
the parameters of self-oscillations in the gas generator.
These options involve the use of a priori given value of the methodological error, which is due to the
approximation of the trigonometric function. To determine the amplitude of self-oscillations in the gas generator of
the hydrogen storage and supply system, a biquadratic algebraic equation was obtained, the root of which is a
function of the time parameters of the gas generator of the hydrogen storage and supply system, the parameters of
the nonlinear element - the pressure sensor, as well as the generalized transmission coefficient. It is noted that the
minimum amplitude of self-oscillations is determined by the value of the dead zone of the pressure sensor. A
condition was obtained to ensure the minimum value of the amplitude of oscillations in the gas generator of the
hydrogen storage and supply system and it was shown that for its implementation it is advisable to vary the gain
coefficient of the amplifier in the electric motor control circuit. The results obtained are generalized in the form of
graphical dependencies that provide express estimates of the parameters of self-oscillations in the gas generator of
the hydrogen storage and supply system when monitoring its technical condition.
The scientific novelty of the research lies in the fact that using the Mikhailov equation, which includes as a
component the equivalent complex transfer coefficient of the gas generator pressure sensor, the parameters of self-
oscillations used to implement the option of monitoring its technical condition have been determined. The practical significance of the research lies in the fact that monitoring the technical condition of the gas generator can be carried out without the use of equipment that provides the formation of test signals.
