ABSTRACT:
A method for the detection and regulation of a spring moment and a difference speed in rotationally driven systems in which a drive unit can be viewed as an elastically coupled two-mass system. The spring moment and the difference speed are determined without direct measurement of the actual load speed or the load position. This is done by comparison of the actual motor speed influenced by the spring moment and a simulated actual motor speed. The resulting difference speed and spring moment are directly proportional to the actual difference speed and the actual spring moment and can be supplied to the regulating system of the motor for regulating the intrinsic oscillations of the system.
