Abstract
A linkage control system for a machine having a linkage and a work implement is disclosed. The linkage control system has an operator input device configured to control the movement of the linkage, at least one actuator configured to respond to the operator input device to control the movement of the linkage, and at least one sensor configured to generate a signal indicative of sensor data on at least one actuator. The linkage control system has a controller in communication with at least one actuator, at least one sensor, and the operator input device. The controller is configured to calculate the position of the linkage, to detect anomalous sensor data from at least one sensor, and to predict the position of the linkage and work implement based on a last known accurate position, a last known accurate sensor data, and the operator input device.
