Review on control systems and control strategies for excavators

Abstract The product performance of excavators continuously improves with industrial development. However, unsighted improvements in the cannot meet emission standards. Therefore, considerable research on energy conservation, high efficiency, and accurate control strategy should be conducted. At present, power matching is performed because inconvenience transmission. technical advantages hybrid provide a better direction for energy-saving excavators. Intelligent algorithms, such as sliding mode time-delay control, are added to system improve trajectory accuracy excavator control. intelligent operation reduces requirements operating environment economy remote, complex, dangerous spaces. statuses matching, autonomous reviewed. Finally, six conclusions about current status drawn.
