“…During the walking of tracked vehicles, the vehicles will be interfered by various internal and external factors, such as system parameter changes, load changes, etc. [1][2][3] . To improve the accuracy of vehicle straight walking, it is necessary to improve the straight walking anti-interference capability of the vehicle hydraulic walking system.…”

In this paper, a synchronization control method is proposed to address the synchronization issue of the pump-controlled motor circuit of the hydraulic walking system. A double closed loop with fuzzy PID control method by applying this method is first utilized, which will reduce the error between each motor and the desired speed; then it is a cross-coupling synchronization method to reduce the speed error between two motors; finally, the purpose of synchronization of two motors will be realized. The simulation study showed that the synchronization accuracy will be effectively improved by employing this method. In addition, the tracking time can be shortened by 72% without overshoot when adjusting the speed of one side motor. After adding a sudden disturbance, the stability adjustment time is the shortest as well, and the overshoot is the smallest. Eventually, by using cross-coupling control, the synchronization error of motors on both sides will be reduced by 71%, and the error elimination time shortened by 21%. It meets the requirements of stability and synchronization control.

“…They have the highest energy efficiency of all EMs, the highest rated and maximum torque values per unit of mass and volume, and high torque overload. 20,21 Furthermore, they have high performance with the ability to operate at a higher torque than the rated torque for a small interval of time, and precision of the drive control, which makes them suitable for motion control applications such as mobile machines. 22 The PMSM can be categorized into two different types, the surface-mounted permanent magnet motor (SPMSM) and the internal permanent magnet motor (IPM), depending on the mounting of the magnets on the rotor.…”

Environmental concerns have pushed toward electrified technologies for off‐road vehicle actuations that can lower greenhouse gas emissions and reduce energy consumption. Replacing a central diesel engine with a dedicated electric machine (EM) as a prime mover for the hydraulic supply offers several opportunities for so‐called ePumps (aka electric‐driven pumps) to maximize energy efficiency and limit the usage of electric materials. This paper discusses the impact of different choices for the ePumps architecture (i.e., fixed vs. variable displacement pump; variable speed vs. fixed speed electrical machine), and on their main design parameters in terms of size and efficiency. Although the procedure followed in the study could be extended to different types of electric and hydraulic units, the paper particularly considers ePumps based on permanent magnet synchronous machines combined with axial piston machines. The importance of properly considering the ePump drive cycle and its cooling requirements is taken into account while addressing energy efficiency, mass, and overall compactness of the solution. The results show that an ePump based on a variable displacement pump, when compared to fixed displacement ePumps, reduces the electrical machine size both in volume and mass up to 40%, when the high‐pressure demand is not combined with high flow rate demand, thus decreasing the cost of the EM. In all drive cycles, the variable speed EM–fixed displacement pump architecture has a higher efficiency, ranging from 1% to 5%, compared to the case of fixed speed EM–variable displacement pump. Finally, the paper compares the advantages and shortcomings of each ePump architecture presented, based on representative drive cycles.
