Influence of the gear ratio on the dynamics of a control-system drive

The influence of the gear ratio on the dynamics of the drive between the motor and the object of control is considered. First, the simplest model is considered: processing of a constant control signal by a drive with a motor whose mechanical characteristic is linear. The combined inertial and active load of the drive’s output component is constant. Then attention turns to models of drive systems with a motor of the same type in the processing of a harmonic control algorithm. Possible limits on the mechanism’s gear ratio are identified on the basis of the specified vibrational amplitude and the limits on the input signal’s frequency.
