The paper presents a brief analysis of the existing mathematical models of membrane processes, allowing to obtain the dependence of the solvent volume flow and the concentration of the separated solution on the time of the membrane separation process. The models allowing to calculate the concentration and solvent specific flow at the membrane devices exit for industrial membrane processes are also considered. One of the considered models is modified due to the introduction of Reynolds criterion and the energy consumption for membrane separation with the application of electric fields. The electro-membrane process is widely used in the food industry, in particular in the production of whey protein concentrates from secondary dairy raw materials.

The article is devoted to the general problems of the theory of reliability of power supply systems. A mathematical description of the operation of power supply systems has been developed taking into account the hierarchy of their structures and the interaction of their elements with an assessment of the impact on them of a wide range of random disturbing factors. When determining the parameters of temporary interaction of elements depending on the moments of switching on and off of electrical and technological equipment, three situations are possible: simultaneous switching on of equipment according to a given operating program, operation of equipment in accordance with a technological process using a previously known algorithm, and also the case when on and off are independent and subject to random law. To assess the dynamics of the process under consideration, it is proposed to determine the distribution laws for the durations of working states and pauses for the joint operation of equipment groups.

The paper studies the stress-strain state (SSS) of a model closed wing of an airplane by the method of experimental calculation analysis using speckle holographic interferometry. As a result of the study of the SAT model of the wing, reveal and clearly demonstrate the capabilities of experimental-computational analysis using speckle holography. An experimental study of the stress-strain state of structures was carried out using an experimental loading device. An algorithm has been developed for the experimental-calculated analysis of the stress-strain state of structures using speckle holography and the results of studies are demonstrated using the example of an experimental loading device. The research results can be used to develop the concept of the power circuit of an aircraft with a closed wing system, which is considered structurally one of the most promising, as it has many potential advantages associated with reducing its weight, increasing the rigidity of the structure and reducing its deformations, with the ability to directly control the lifting and lateral forces.

We are discussing the origin and meaning of the notion of neighborhood system. The transition from continuous to discrete erases the distinction between dynamic systems (i.e. systems of first order ordinary differential equations) and evolutionary partial differential equations: in both cases we get the same object, discrete dynamic system. The dynamic neighborhood systems can be considered as a subclass of dynamic discrete systems, corresponding substantially to evolutionary partial differential equations and characterized by the “sparsity” of the entering of variables in the equations. This “sparsity” is described by a digraph, which is called the neighborhood structure, while the neighborhood system itself can be considered as a system “over” this neighborhood structure.

Important requirements for the modern electric drives are the high overload capacity and a wide range of speed control. A two-phase adjustable low-power drive has these properties, but its implementation in small-scale mechanics is hindered by the need a frequency converter that provides a three-phase power grid into a two-phase network, which is important when the power of the mechanisms increases. Previous studies have already shown the possibility of using a typical frequency converter based on a three-phase full-bridge voltage inverter applying space-vector PWM method. The switching frequency of the inverter remains, unfortunately, relatively high. It is not possible to reduce this frequency without degrading the harmonic composition. The goal of this work is to develop an algorithm for controlling the two-phase electric drive system, while reducing the numberof commutations of the switching devices of the three-phase inverter, and at the same time keeping the deviations of the instantaneous values of the phase currents close enough to the reference.

Well-known methods for identification symmetric periodic motions and assess their stability in continuous relay feedback control systems. Time discretization can lead to the emergence of many available symmetrical periodic motions. In a sampled-data relay control systems (RCS) there may be microchaotic oscillation. In this paper we propose a criterion to evaluate the stability of such movements. Self-oscillating RCS operating in discrete time are considered. Using the method of a discrete locus of a relay system all possible symmetrical periodic motions in an autonomous discrete relay system are identified. Next, the stability of the limit cycle with the maximum possible repetition period is evaluated. The method of analysis of global asymptotic stability of periodic motions developed for a continuous RCS, for a class of discrete systems is used. The developed method is based on the use of the Lyapunov function and the theory of linear matrix inequalities (LMI).
