Abstract:
1. A method for controlling output torque in a rotating mechanical system, comprising: a. providing an input torque generating device; b. providing a gearbox connected to said input torque generating device, said gearbox having a gearbox input shaft connected to said torque generating device and a gearbox output shaft; c. providing a load, with said load receiving toque from said gearbox output shaft through a load shaft; d. determining a load torque for said load; e. providing a torque damper motor which rotates in unison with said load shaft, with said torque damper motor being located between said gearbox output shaft and said load; f. defining a desired gearbox output torque; g. providing a damper motor controller which controls the torque created by said torque damper motor; and h. controlling said torque created by said torque damper motor so that the sum of said torque created by said torque damper motor and said load torque is approximately equal to said desired gearbox output torque.
