Kinematic model of motion of the hexapod robot control system

The study of the trajectory of the robot limb movement for the control system of a walking hexapod robot was carried out. A kinematic model of a hexapod robot has been developed. The equations connecting the values of the movement of the robot limbs and the angles of their location are found. The simulation of the obtained kinematic model made it possible to determine the trajectories of the limb movement of the hexapod robot.

Keywords: hexapod robot, kinematic model, control system, robot limb, foot movement trajectory.

Synthesis of fuzzy-logical control system with application of PID-regulation of technological processes of dynamic objects

This paper is devoted to the synthesis of fuzzy-logical control system using PID control for technological processes of dynamic objects. Under conditions of uncertainty and constant dynamics of technological processes, it is necessary to have an effective control that allows to compensate perturbations and achieve the set goals. Synthesis of the control system is carried out on the basis of PID-regulator and fuzzy logic. PID controller provides fast and accurate response to changes in input signals and control errors. Fuzzy logic allows to express fuzzy dependencies between input and output variables of systems, unpredictability and nonlinearity of object dynamics. The questions of research of dynamics of control system of technological processes with application of fuzzy-logic PID-regulator are considered. The methodology of synthesis of fast-acting algorithm of fuzzy-logical inference on the basis of neuro-fuzzy network, which allows to exclude empty and null solutions in the problems of defining the architecture and calculating the weights of the process neural network arcs, is proposed. To correct the parameters and structure of the fuzzy-logical PID controller it is proposed to include an adaptation block in the control system loop. Adaptation is carried out taking into account the states of the object and external influences. The developed models and algorithms are tested for adequacy on a real example by solving the problem of controlling the absorption process of soda ash production and comparing the results with the real object.

Keywords: automatic control system, dynamic objects, adaptive control, robustness, fuzzy logic, synthesis, velocity gradient algorithm.

Atmospheric boundary layer monitoring system based on a tethered multi-rotor platform

To organize educational and sports events in the field of ultralight aviation, it is critical to have up-to-date information on the state of the meteorological situation. In addition, flight support can be significantly influenced by the heterogeneity of air masses, terrain features and various meteorological phenomena, such as thermal activity, wind shear and others. To collect up-to-date information about the current state of the atmosphere, the possibility of using an information-measuring instrument complex based on a multi-rotor platform with external cable power supply, equipped with a system for meteorological measurements, is being considered.

Keywords: UAV, meteorological complex, information-measuring system, multi-rotor vehicle.
