Aerospace Instrument-Making Annotation << Back TRANSFORMATION OF SPECTRAL TRIAD OF REAL VARIABLE FUNCTION BY A MATHEMATIC STRUCTURAL MODEL OF CONTROL DEVICE I.Ya. Ogurtsov A new transformation of real variable function – the spectral triad, is transformed by a linear mathematic structural model of control device. Equations of connection of spectral triad are determined on the input and output of the device. Equations of connections are the new forms that recall frequency characteristics of linear model of the device. According to equations of connections the spectral triad on the input is translated into spectral triad on the output of the device. Coupling coefficients are applied by extreme values and by the arguments of the extreme values. They are theoretically substantiated and can be calculated by experimental data very much like amplitude frequency characteristics. These characteristics serve as a new form of description of dynamic properties of the device. Key words: transformation of function, spectral triad, mathematic model, frequency characteristics, coupling coefficients. E-mail: office@nwpi.ru
