The subject of this work is the problem of describing the dynamic behavior of the price in the market of one product. The typical balance of interaction of supply and demand functions depending on the price is considered. The dynamic model of price evolution is based on the assumption that the deman...

Objectives. The solution to the relevant problem of identifying systems with multiple nonlinearities depends on such factors as feedback, ways of connecting nonlinear links, and signal properties. The specifics of nonlinear systems affect control systems design methods. As a rule, the basis for the...

This article is devoted to the  development of analytically  described self-oscillation  stability  research  technique.  The case when  the  linear part  of the  system contains transfer function with a zero pole is considered. Typically the transfer function study,  where  the  numerator degree  i...

A new optoelectronic oscillator (OEO) is implemented for a novel self-sustained flat-topped self-oscillating optical frequency comb generator (SO-OFCG), which can be deployed in terahertz optical transmission. The OFCG is designed from a cascaded configuration of an electro-absorption modulator and...

Designing a modern flight vehicle is associated with the need to solve many scientific and technical problems. These tasks include the prevention of insecure self-oscillations in flight, taking into account the elasticity of the structure. These problems relate to dynamic aeroelasticity, a science t...

Spline couplings, due to their high reliability and strength parameters, are widespread not only in mechanical engineering. The ability to transmit high torque with a sufficiently long service life has led to the extensive use of these couplings in the aircraft industry. Since this unit is under hea...

The results of investigations on the mechanism and kinetics of the polycondensation of organosilanols are reviewed. The review consists of two parts. In the first part data on the kinetics of monomer condensation are given. The second part considers the condensation of siloxanols.

We consider chains of identical diffusive weakly coupled oscillation systems with different conditions on coupling on a chain bound. We suppose that every interacting oscillator undergoes Andronov–Hopf bifurcation, and the coefficient of coupling is proportional to the supercriticality value. For this c...

Introduction. Modern methods of stabilizing a frequency of self-oscillations use an improvement of the stability of reactive parameters of the self-oscillators circuit and an increase in the quality factor of an oscillating system. It is also possible to improve the frequency stabilization based on...

The article presents a method for creating a system with specified stability properties. The system parameters are obtained under the conditions of the energy balance between the power supplied and dissipated in the process of self-oscillations. The effect of stabilization of initially unstable syst...

A comparative evaluation of the results of analytical calculation of the self-oscillations and stability analysis techniques is provided developed for symmetric self-oscillations with repetitions through halfperiod and asymmetric with repetitions through the period.

Introduction. Modern precision radio systems impose stringent requirements on the quality of the reference signal sources used. Various approaches are used to create sources of reference signals in the microwave range – micro-wave self-oscillators (SO). A promising direction in the development of su...

This review summarizes the findings of some published studies that have explored the influence of various delays (elasticity, damping, and self-oscillatory mechanism of excitation) on the dynamics of classes (or types) of mixed oscillations (MO) without and with consideration of the interaction betw...

Objectives. The development of a mathematical dynamic system model is necessary for analysing vibrational motion during the metal  cutting processes. The mathematical model of the dynamic system is considered to be defined if the system parameters that  unambiguously determine its state are known an...
