Moving member control apparatus and imaging apparatus incorporating the same

Abstract

The moving member control apparatus of the invention is characterized by comprising a base part 10, a moving part 30 capable of moving relatively with respect to the base part 10, a first driving portion 71 that applies driving force to the moving part 30, a second driving portion 72 that applies driving force to the moving part 30, a first instruction portion that gives an instruction to the first driving portion 71 about a displacement position or where to move, a second instruction portion that gives an instruction to the second driving portion 72 about a displacement position, a first position acquisition portion 34a that acquires a real position of the first driving portion 71, a second position acquisition portion 34b that acquires a real position of the second driving portion 72, a first deviation calculation portion that calculates a first deviation eX1 between a position rX1 instructed by the first instruction portion and a real position X1pos acquired by the first position acquisition portion 34a, a second deviation calculation portion that calculates a second deviation eX2 between a position instructed by the second instruction portion and a real position X2pos acquired by the second position acquisition portion 34b, a correction portion 2 that products a first correction signal rX1 and a second correction signal rX2 corrected for the first deviation and the second deviation, respectively, depending on a difference between the first deviation and the second deviation, and a control portion 3 that receives the first correction signal rX1 and the second correction signal rX2 to control driving the forces of the first driving portion and the second driving portion, respectively.
