Class Information
Number: 318/560
Name: Electricity: motive power systems > Positional servo systems (e.g., servomechanisms)
Description: Subject matter comprising a system which maintains a prescribed relationship between the position of a member or a function of the position and the value of a arbitrarily varied command signal by detecting an error between the actual position of the member or the actual value of the function of the position and the position or value commanded by the signal and controlling a motor of the servo system in response to the detected error.
