1. An agricultural method for automatically controlling a position of a harvesting implement of an agricultural harvester, the harvesting implement being movably supported relative to a chassis of the agricultural harvester, the agricultural harvester further comprising a cab movably supported relative to the chassis, the method comprising:
receiving, with a computing system, implement-based inertial movement data generated by an implement-based inertial measurement unit (IMU) supported on the harvesting implement;
receiving, with the computing system, vehicle-based inertial movement data generated by a vehicle-based IMU supported on at least one of the cab or the chassis of the agricultural harvester;
determining, with the computing system, a relative movement parameter of the harvesting implement relative to the at least one of the cab or the chassis based at least in part on:
comparing a vehicle acceleration of the at least one of the cab or the chassis from the vehicle-based inertial movement data to an implement acceleration of the harvesting implement from the implement-based inertial movement data; and
determining that the at least one of the cab or the chassis is experiencing a reactive acceleration based at least in part on the vehicle acceleration being opposite in direction from the implement acceleration; and
controlling, with the computing system, an operation of an implement actuator based at least in part on the relative movement parameter.
