Claim 13:
14. A system that dampens torsional oscillation of an object that rotates in a horizontal plane, the system comprising:
a motor that is configured to rotate the object in the horizontal plane;
a motor control that is operably coupled to the motor and is configured to control the motor based on at least one input; and
an electronic module that is communicatively coupled to the motor control, the electronic module comprises:
a housing;
a memory that is disposed within the housing and is configured to store a mass-dependent value of the object or of rotating parts of the system rotating in the horizontal plane; and
a processor that is disposed within the housing, the processor being configured to:
receive the mass-dependent value of the object or of the rotating parts of the system,
store the mass-dependent value of the object or of the rotating parts of the system in the memory,
calculate a torsional oscillation dampening signal using an algorithm that is based at least in part on the received mass-dependent value of the object or of the rotating parts of the system, and
transmit the torsional oscillation dampening signal to the motor control causing the motor control to operate the motor based on the torsional oscillation dampening signal thereby dampening torsional oscillation of the object rotating in the horizontal plane.
