Description

technical field

[0001] The invention relates to a trajectory control system and method for a working device of a hydraulic excavator. Background technique

[0002] 1. Hydraulic excavators are mainly used in earthwork construction and other occasions. The driver needs to have a certain degree of proficiency in manipulating the working device of the hydraulic excavator. In the process of straight line leveling and slope excavation, it often depends on the driver's operating experience. Complicated actions increase the labor intensity of the driver and reduce labor productivity. The use of automatic manipulation can greatly improve the operation efficiency and operation quality, and better complete the operation tasks.

[0003] 2. Some existing control devices fail to take into account the influence of changes in the hydraulic excavator's speed, load, and attitude of the working device on the control performance, resulting in poor stability and control accuracy, and affecting ...
