| Abstract |
This paper is concerned with principles of the estimation of non-measurable state variables and
external torque load in drives with an elastic motor shaft (two mass system). In many drive systems,
the use of resilient couplings between the motor and the processing machine, due to elastic shafts and
gears, is often unavoidable. In this paper, speed control for torsional vibration suppression in a 2-mass
motor drive system is studied. The speed control method which uses a state and disturbance observer
with a PI controller has a better control response than a typical PI speed controller. |
