    Abstract: Embodiments of an intelligent hinged boom excavation system include a hinged boom assembly terminating in an excavation tool, an electro-hydraulic (EH) actuation subsystem, and boom assembly tracking sensors providing tracking data indicative of excavation tool movement. A controller architecture is operable in an excavation depth limiting mode in which the controller architecture: (i) tracks a current position of the excavation tool relative to a virtual excavation floor utilizing the tracking data provided by the boom assembly tracking sensors; (ii) determines when an operator-commanded movement of the hinged boom assembly will result in breach of the virtual excavation floor by the excavation tool; and (iii) when determining that an operator-commanded movement of the hinged boom assembly will result in breach of the virtual excavation floor, controls the EH actuation subsystem to modify the operator-commanded movement in a manner preventing breach of the virtual excavation floor by the excavation tool.
