Excavator as well as control method and control device thereof

Номер: CN102912817A
Автор: Shan Xiaoning, Yang Chao, Zhao Han, Hu Yuqin
Принадлежит:

The invention provides an excavator as well as a control method and a control device thereof. The control method for the excavator comprises the following steps of: obtaining the rotating angle of the excavator and the included angle between a movable arm and a frame in real time; obtaining the required movement of a hydraulic actuator of the excavator according to the numerical ranges of the included angle and the rotating angle; and sending a control instruction corresponding to the movement to the hydraulic actuator. According to the actual working condition, the coordinated movement conditions for the movable arm and rotation can be realized by utilizing the preset matching relation between the movement of the hydraulic actuator and the included angle and the rotating angle so as to meet the requirement for coordinated movement of the actual working condition, realize the coordinated control on an oil cylinder of the movable arm and a rotary motor, and real-time manipulation of operating ...
