摘要

A servomechanism control system comprising: means (12) for generating a command signal representing a desired physical quantity; means for actuating a driven element (18) to output said physical quantity in accordance with said command signal; means for measuring said output physical quantity and comparing it with said command signal; means (14) for generating an error signal representing the difference between said command signal and said measured output; and means for providing said error signal in a feedback loop (16) having a variable gain to actuate said driven element in a fashion so as to reduce said error signal to a zero value, wherein said variable gain is provided in accordance with a function related to the absolute value of said error signal and the absolute value of said command signal. 676 כ" א באייר התשס" ד - May 12, 2004
