Abstract
A controller that can perform high-precision synchronous control even when the speed of a master axis changes and a machine learning device are provided. The controller includes the machine learning device that learns the future predicted position of the master axis with respect to the operation state of the master axis, and the machine learning device includes a state observing section that observes, as a state variable indicating the current state of an environment, master axis predicted position data indicating the future predicted position of the master axis and master axis operation state data indicating the operation state of the master axis, a judgment data acquiring section that acquires judgment data indicating the properness judgment result of a synchronization error of a slave axis, and a learning section that learns the future predicted position of the master axis by correlating the future predicted position of the master axis with the master axis operation state data by using the state variable and the judgment data.
