AUTOMATIC DYNAMIC ERROR COMPENSATOR Abstract of the Disclosure An automatic dynamic error compensator for compen- sating the position error arising within a servo drive system includes a measuring head which is operative to measure the relative indicated position of two or more measuring vanes on the movable member. The measuring head, together with a feedback transducer, that measures indicated movable member position, are coupled to a feedback system. The feedback system determines the indicated movable member position from the feedback transducer reading and then compares the indicated mov- able member position to the known vane position upon occurrence of a vane crossing to yield a compensating value.
