<P>PROBLEM TO BE SOLVED: To provide a signal processor and a control system, reducing a delay amount when detecting velocity information without increasing cost. <P>SOLUTION: An interpolator 100 receives a sin signal and a cos signal from a center 22, and outputs velocity V and a position P to a control part 31. In the control part 31, the velocity V outputted from the interpolator 100 is directly inputted to a velocity control element 40 of a feedback path related to velocity. The position P outputted from the interpolator 100 is directly inputted to a position control element 42 of a feedback path related to a position. A sampling period in detecting the velocity information does not depend on a sampling period on the control part 31 side to reduce the delay amount when detecting the velocity information. It is not necessary to add hardware or the like to the control part 31 side, so that the cost increase can be prevented. <P>COPYRIGHT: (C)2008,JPO&INPIT |
