Trajectories Planning and Simulation of a Backhoe
These models were used for the excavator boom, arm and bucket hydraulic actuators dynamics analysis and control to minimize vibrations of the excavator bucket during the excavation works. In [15] in order to investigate the skilled operator behaviour, an excavator model with the help of SimMechanics and SimHydraulics was obtained.

[PDF] Study on Modeling and Control of Excavator
An excavator is a typical hydraulic heavy-duty human-operated machine used in general versatile construction operations, such as digging, carrying loads, grounding and dumping loads. However, operating excavators in the hazard environment such as earthquake, nuclear decomposition etc is not suitable for human to operate on site. Therefore, automation in excavator has been …
