摘要
An active eddy current damper and a control method thereof, and a load cell module and a weight discriminator including the same are disclosed. An active eddy-current damper is a damping portion, which is a movable conductor and damping portion which is connected to an operator and moves according to an operator's motion. An eddy current generated by an electromagnetic force generated by a relative movement between a movable conductor and a damping portion is used as a damping force, And a damping control section for actively controlling the damping force of the damping section based on the physical characteristics of the damping section and the object to which the weight is applied and the characteristics of the motion of the operator. The damping control unit includes a natural frequency calculation unit for calculating a natural frequency of motion of the movable conductor, a target frequency determination unit for determining a target frequency of motion of the movable conductor in accordance with physical characteristics of the measured object, a calculated natural frequency and a determined target frequency A damping coefficient modeling unit for modeling the damping coefficient related to the damping force of the damping unit with reference to the damping force, and a control parameter determiner for determining a control parameter related to the operation of the damping unit with reference to the damping coefficient and the target frequency. According to the present invention, the damping force of the eddy current damper can be actively varied according to the weight of the measured object and the required measurement speed, and the service life of the load cell can be remarkably increased.
