An automated system including a control target device and a control device which controls the control target device, in which it is possible to accurately estimate whether maintenance of the control target device is required and a portion requiring maintenance. The control device is an adaptive control device including a position control system, an adaptive identifier which estimates a parameter indicating a state of a control target device based on a control command and a control target output from the control target device, and an adaptive compensator which, based on the parameter which is estimated by the adaptive identifier, compensates the control command from the position control system to the control target device such that the control target device performs a planned operation regardless of a change in the parameter.

A component mounting machine moves a mounting head from a supply position Pto each of mounting positions Pand Pof a circuit board CB via an imaging position P. Further, the component mounting machine performs control such that the mounting head moves in a direction of movement at the time of imaging that is either of an X-axis direction or a Y-axis direction when passing through the imaging position P. The component mounting machine determines the direction of movement at the time of imaging, according to a first X-axis distance Lx and a first Y-axis distance Ly from the imaging position Pto each of the mounting positions Pand P

After a component picked up by a suction nozzle is moved in an XY direction towards target XY coordinates, a waveform of a vibration (vibration waveform) in the Y direction arising in the component after the component has arrived near the target XY coordinates is measured, and control is performed such that the component arrives at a target Z coordinate (value zero) when a displacement y of the component crosses a node of the measured vibration waveform.
