摘要： A torque command value and an acceleration detection value are accumulated when a driven portion is subjected to acceleration/deceleration driving, and, from a ratio between the two, inertia of a movable portion is calculated. By executing the acceleration/deceleration driving about a position where influence of gravity torque is zero, the influence of the gravity torque included in the torque command value before and after the center position is offset, whereby inertia can be estimated correctly even with a machine structure in which the influence of gravity differs depending on the position of the motor.

摘要： A method and system for identifying a moment of inertia (MOI) of a work piece includes coupling the work piece to a manipulator assembly such as a 6-axis robotic arm or 3-axis gimbal. The manipulator assembly includes a force/torque sensor and a motion feedback sensor. The manipulator assembly moves the work piece with three-dimensional motion. Force, torque and movement measurements are made as the work piece moves. The MOI is identified according to the force and torque measurements and rotational accelerations derived from the measured movement. The measurements may be used to identify the products of inertia (POI) and center of mass of the work piece.
