Abstract
A system for controlling the operation of an industrial machine during crowd runaway conditions. The system includes a controller that monitors and compares an actual crowd system state (e.g., an actual dipper position) with a requested crowd system state (e.g., a requested dipper position from the operator). If the controller determines that the crowd system is behaving contrary to requested crowd system behavior, the controller adjusts a crowd parameter, such as a crowd motor torque, to resolve the runaway condition.
