| Abstract: | In this paper, it is discussed that the engineering method for realizing the technologic control of large excavators with power transmission. The key techniques are studied in great depth and applied to engineering practice, such as non-loop-current control, locked-rotor characteristics, the optimization of double-loop regulation, load balancing, vibration reducing shock, and over-current protection. And the imported analog system is upgraded with digital scheme. The realization has the excellent effect in the copper mine of DeXin ＂ operation. |
