Mathematical Model Of An Industrial Robot Built On The Basis Of Linear Motion Mechatron Modules, Matyokubov Nurbek Rustamovich, Rakhimov Temurbek Omonboyevich

Chemical Technology, Control and Management

The use of Industry 4.0 technologies in modern production serves to increase production efficiency. Robots and robotic complexes with innovative intelligent control are widely used in industrial production. However, studying their mechanical part, linear motion mechatronic modules and control system is a complex object. The variety and complexity of control methods and operating modes negatively affects the operator's working time and production productivity. In such cases, it is necessary to improve control methods and develop technologies used in industry, including robots and robotic manipulators, which allow to perform short movements with high accuracy and speed. In the article, the mathematical …

Methods For Control Of The Technical And Operational Parameters Of Vehicles, Erkin Uljaev, Utkirjon Murodillaevich Ubaydullaev

Chemical Technology, Control and Management

The necessity of automating the control and evaluation of the technical and operational indicators of motor vehicles (ATS) is substantiated. A classification of the main technical and operational indicators of vehicles has been carried out. Motor vehicles can be classified according to dimensions, weight, carrying capacity, cross-country ability, speed, maneuverability and other indicators. A brief review and analysis of well-known technical means of foreign firms, designed to automate the control and evaluation of the technical and operational indicators of vehicles and agricultural machinery, has been carried out. It is noted that more than 90% of the considered devices and means …

Topological Interpolation Method For Modeling Dynamic Systems, Isamiddin Xakimovich Siddikov, Dilnoza Maxamadjanovna Umurzakova

Chemical Technology, Control and Management

The method of simulation structural-complex continuous-discrete control systems is discussed. For simulation and calculation of dynamic processes in continuous-discrete systems topological interpolation method is proposed, based on application of hybrid methods of space of state variables and interpolation of signals. The essence of the method is that the dynamics of the investigated system, considered at the final interval, is broken down into subintervals, on each of which the processes are described by linear ordinary system differential equations. The computational efficiency of the proposed method was evaluated by comparison with standard methods such as the Runge-Kutta-Merson method. The use of this …

Efficiency Of Functioning Of Intersections With High-Intensity Traffic And Pedestrian Flows, Aziz Ernazarov

Technical science and innovation

The article studies the interaction of traffic and pedestrian flows with high intensity at regulated intersections to improve the capacity of such intersections. To study the parameters of traffic flows, in particular, the length of traffic jams, a traffic flow model was used. To study the parameters of traffic flows, in particular, the length of traffic jams, a traffic flow model was used, which includes a psychophysiological model of following a vehicle that moves in front, for the longitudinal movement of vehicles and a model that is based on the rules of the road, for turning traffic. The research methodology …

Techniques To Solve Decision-Making Problems, Dilnoz Tulkunovna Muhamediyeva, Bekmuratov Fayzievich Tulkun

Chemical Technology, Control and Management

Solving decision-making problems in poorly formalized systems only with the help of deterministic and probabilistic methods is insufficient. To do this, it is necessary to widely apply the methods of hybrid intelligent systems and, especially, the methods of “soft” calculations (SoftCalculation, SoftComputing) and the directions of ComputationalIntelligence — intelligent computing technologies that are emerging on this theoretical and methodological base. An immune - fuzzy algorithm for the synthesis of fuzzy inference systems (FIS) is proposed. A two-stage adaptive FIS synthesis algorithm is described. At the first stage, the initial fuzzy parameters are clustered in order to reduce the number of …
