Subject of the inquiry: steering wheel of self-driven energetic vehicle means.
Aim of the inquiry: the aim of this inquiry is to rise the stability of the motion and conducting of self-driven means by rational choice of transmission ratio of the steering wheel.
Methods of inquiry : the analytical and experimental research methods are used in the work based on methods of automatic regulation theory.
The results achieved and their novelty: the character of the influence of the transmission ratio quantity on the sensitiveness of the machines the control and stability of the motion are used
The mathematical models for calculation of parameters of the motion of selfdriven energetic means with hydro-huged characters of the steering wheel and the choice of mounting coordinates of carried out hydrocylinders are worked out.
Practical value: the recommendations on the choice of transmission ratio of steering wheel and mounting coordinates of carried-out hydrocylinders rising stability of the motion and improving conduction of self-driven energetic means are worked out.
Mathematical models allowing to realize rational choice of parameters of steering wheel on the stage of project are created.
Degree of embed and economic effectiveness: recommendations on the choice of the quantity of transmission ratio of steering wheel and calculated definition of rational parameters of mounting hydrocylinders of the wheel implement are accepted for the usage in SSC (GAO) "Tashkent Tractor Plant".
Sphere of usage: tractor and agricultural machine-building.
The paper proposes a method for synthesizing an adaptive fuzzy synergistic controller with discrete time for indefinite nonlinear dynamic objects, with changing parameters in time. The synthesized adaptive controller takes into account the non-linear nature of the object, allows its parameters to adapt to environmental changes: The synthesis of the controller is carried out by the hybrid application of the methods of the theory of synergistic control and fuzzy system and gives the system asymptotic stability and t d the desired dynamic properties of the control system, with the ability to adapt to changes in the parameters of the object. The proposed method of synergistic control guarantees the reliability and asymptotic stability of the control system and makes it possible to use typical and atypical control laws. To overcome the difficulties associated with the uncertainties of the function of the states of objects, the use of a neural network model of the Mamdani Type is proposed. A sigmoidal function is used as t the membership function, which is distinguished by the simplicity of implementation and the possibility of differentiating input wariables. The resulting control law has an analytical dependence, which significantly increases the possibilities of its implementation on microcontrollers. The simulation results by example showed the effectiveness of t of the proposed method relative to the known ones

Structural transformations in the economy of Uzbekistan require new approaches to the system of economic management. In the article, the authors define the main directions of the country's economic development in modern conditions and propose certain ways to form a new system of economic management. First of all, it emphasizes the need to form a flexible system of economic management, providing for the reduction of state interference in the activities of economic entities. It was determined that the second most important direction of economic development is poverty reduction and employment expansion.
As a key factor of reforms in the system of economic management, it is proposed to consider the institutional factors of market transformations and take into account their effect. At the same time, it is proposed not only to develop market management mechanisms, but also to define clear boundaries for the use of administrative instruments.
The importance of the country's main resource - accumulated human capital is especially emphasized. A number of measures are proposed to create a modern system for the reproduction of human capital
This article addresses the issues of corporate governance questionnaire currently used to assess the system of corporate governance in Uzbek Joint-stock companies and proposes a new Corporate Governance Scorecard based on OECD principles to fulfill the requirements of the “Roadmap” for the implementation of the Capital Market Development Program in 2021 – 2022.
This article discusses issues related to the structure of modern information, communication and digital technologies in the agricultural management system. Also, based on the study and analysis of the accelerated implementation of information, communication and digital technologies in the agricultural management system, a functional model of interdependence is recommended.
