“…One of the most popular areas in the development of robotic machines is wheeled robotic platforms facilitating technological processes of preparing the feed mixture, distributing it, as well as the process of manure removal. The relevance of creating robotic autonomous controlled systems with electric drive can be traced in other areas of consumption, as was described in studies by Chen, Q. et al [6].…”

The goal of the research is a mathematical modeling of the motion process of a wheeled robot along a given trajectory with the turn drill. Matlab software with the Simulink option package was used as the environment for artificial modeling of the motion process. In order to control the movement of a wheeled robot using the computational and graphic methods, a kinematic and dynamic model of a wheeled robot was determined. The robot has two independent drive wheels located on the same axis and operating on electric traction. Based on the obtained mathematical correlations, a nomenclature of artificial components was formed in the Matlab (Simulink) environment, which made possible to simulate the process of controlling the robot’s electric drive. A voltage that was twice as different was applied to the electric drive of independent wheels located on the same axis as a reliability check of the mathematical model in the Matlab (Simulink) artificial medium. The artificially simulated motion process of a wheeled robot involved studying the motion process using the “PLOT (X; Y)” function. At the moment of the robot’s movement, the trajectory of the 00 point, which is the center of robot’s mass, for a set unit of time, was obtained. This allowed confirming the reliability of the developed mathematical model for the control system of a multifunctional robot for animal units.

“…GM applied the self-developed hub Energies 2021, 14, 5766 2 of 24 motor to the Chevrolet S-10 pickup truck. The wheel weight increased by only 15 kg, but the driving torque was 60% higher than that of the ordinary Chevrolet S-10 fourcylinder pickup truck [5]. In [6][7][8], the hub motor drive adopts the direct torque control (DTC) control strategy.…”

Research on Decoupled Optimal Control of Straight-Line Driving Stability of Electric Vehicles Driven by Four-Wheel Hub Motors

The optimal control strategy for the decoupling of drive torque is proposed for the problems of runaway and driving stability in straight-line driving of electric vehicles driven by four-wheel hub motors. The strategy uses a hierarchical control logic, with the upper control logic layer being responsible for additional transverse moment calculation and driving anti-slip control; the middle control logic layer is responsible for the spatial motion decoupling for the underlying coordinated distribution of the four-wheel drive torque, on the basis of which the drive anti-skid control of a wheel motor-driven electric vehicle that takes into account the transverse motion of the whole vehicle is realized; the lower control logic layer is responsible for the optimal distribution of the driving torque of the vehicle speed following control. Based on the vehicle dynamics software Carsim2019.0 and MATLAB/Simulink, a simulation model of a four-wheel hub motor-driven electric vehicle control system was built and simulated under typical operating conditions such as high coefficient of adhesion, low coefficient of adhesion and opposing road surfaces. The research shows that the wheel motor drive has the ability to control the stability of the whole vehicle with large intensity that the conventional half-axle drive does not have. Using the proposed joint decoupling control of the transverse pendulum motion and slip rate as well as the optimal distribution of the drive force with speed following, the transverse pendulum angular speed and slip rate can be effectively controlled with the premise of ensuring the vehicle speed, thus greatly improving the straight-line driving stability of the vehicle.

“…However, attempts to massively introduce electric cars did not yield the desired result. This is mainly due to the limited power reserve for an electric vehicle to travel per a single charge of a traction rechargeable battery (TRB) given its low energy intensity [7,8]. In the pursuit of improving the environmental component, it is also a relevant task to preserve other characteristics in vehicles (for example, mileage, economy).…”
