液压挖掘机轨迹智能控制的研究

Study on Tracking Intelligent Control of Working Arms of the Excavator

对挖掘机液压伺服机械手的轨迹提出了一种新的智能控制方法. 利用行程可测量油缸和先导伺服驱动方向阀构成的液压控制系统, 根据要求对动臂摆动机构系统的3个工作臂液压阀进行了有效控制,并给出了系统模型.

To ensure accurate work, high efficiency and low energy consumption of the excavator, we have established a new method that controls intelligently the position and tracking of working arms of the excavator. The measure position cylinder and pilot service driving valve are used to availably control and drive the hydraulic valves of three working arms in the wiggling. A series of fundamental formulae, which describe the controlling theory, are derived.
