This paper presents an adaptive algorithm for position-trajectory control with reference model and estimation of nonlinear circuit unmeasured disturbances. The introduction of a robust observer derivatives in the base controller position-trajectory control, built on the principles of self-adjusting adaptive systems with a reference model, allows to estimate unmeasured disturbance characterized by non-linearity of the second order and higher, and to adapt the parameters of the system in order to reduce or minimize the zero mismatch errors between the control object and reference model. The use of derivatives allows the observer to increase the overall stability of the control system, otherwise, the system loses its stability in short-term effect of the disturbance on the control of high-order object.

One of the problems with exploitation of log trucks is damage to equipment during the process of transportation of wood material and during loading-unloading operations. The authors of the paper suggest equipping a log truck with an innovative protective butting device in order to increase reliability and work efficiency of the hydraulic manipulator. This device will allow aligning the sawn wood ends of wood products, and thus it will allow excluding a chance of protruding of sawn wood ends at an inadmissible scale which prevents forming a neighboring pack of wood products. The device will also allow excluding mechanical damages of a hydraulic manipulator by sawn wood ends of wood products being laid on a load platform. This will increase its reliability and will reduce the expenses on repair works.

The article discusses research methodology of intrapersonal conflict by using the affective component of appropriate social attitudes. We analyze three kinds of internal contradictions. Which are classified by K. Levin as the conflict of ""Desire-Commitment"", ""Avoidance-Avoidance"" and ""Commitment-Avoidance"". They are all connected with a choice of appropriate object or action (equal or different valences) of the two equally probable. The affective component of perception of such internal contradictions is determined by the technology of semantic differential on the basis of the survey conducted at the end of 2016 among students DSTU. For the interpretation of the results used the previously developed technique. The distribution functions of the emotional perception of those conflicts are described in article. Which were calculated as in the linear approximation and a nonlinear lookup psychosemantic model. It is obtained that the average affective perception of the studied conflicts neutral or close to that. But the researched audience is very heterogeneous in its emotional attitude to such conflicts. The distribution function is strongly smeared almost all over the range of levels of perception. While approximately half of the respondents are characterized by positive attitude to internal contradictions. This suggests that positive role of conflicts associated with the resolution of problems of an appropriate level subconsciously affects on estimates. A few unexpected results were obtained by a comparison of the perception of conflicts ""the Desire-the Desire"" and ""Avoidance-Avoidance"". Distribution function for the problem of the choice of two positive options is being shifted to the left, in the negative direction, compared with the function for a choice of two unattractive possibilities. The work has shown the promising use of such figure as the affective perception for researching of intrapersonal conflict. The obtained results possess as General methodical so purely situational, specific significances.

In article the decision of the task of finding of energy saving algorithms of closed control for electric drives is presented. The proposed approach is based on use of mathematical conditions of minimization of energy losses (power invariants) in electric motors as criteria of control. Energetic invariants for the main types of electric motors of a direct and alternating current are provided. For synthesis of energy saving regulators the principles and methods of the synergetic control theory are used. As an example the decision of the task of synthesis of algorithms of energy saving control for the asynchronous electric drive is considered. In case of synthesis of regulators the non-linear mathematical model of the asynchronous motor was used. The algorithm of energy saving control of the asynchronous electric drive providing stabilizing of angular speed of a rotor in the preset value and minimization of losses of energy is presented. Computer modeling of the closed system which completely confirms theoretical prerequisites and allows to draw the following conclusions is carried out. Firstly, the synthesized regulator provides asymptotic stability of the closed system of the relative set steady state. Secondly, at a variation of the external moment of efficiency of the electric motor remains constant and maximum. The comparative chart efficiency of the asynchronous motor in case of the energy saving control and traditional control realized in systems the “Transvector” type is provided.
