ABSTRACT:
A control apparatus for a linear motor includes a linear motor having a moving coil to be moved in response to a drive signal, a position detector for generating a present position signal representing a present position of the moving coil, a target position setter for generating a target position signal representing a target position of the moving coil, a position deviation detector for generating a position deviation signal representing a difference between the target position signal and the present position signal, an inclination angle detector for generating an inclination angle signal representing an angle between a moving direction of the moving coil and a horizontal plane of the earth, a control instruction circuit for amplifying the position deviation signal with characteristics corresponding to the magnitude of the inclination angle signal, and for generating a control instruction signal, and a driver circuit for generating the drive signal corresponding to the control instruction signal.
