This control system comprises: a signal processing unit generating a signal related to the target operating amount of an actuator; a feedback control unit that controls the actuator based on the difference between the signal related to the target operating amount and a signal related to the fed-back operating amount; a feed-forward control unit that controls the actuator based on the signal related to the target operating amount in cooperation with the feedback control unit, and learns the characteristics of the actuator by adjusting a weighting factor based on a teacher signal; and a calculation unit that calculates information related to the deflection of the work machine. The signal processing unit corrects intermediate information, which is generated in the process of generating the signal related to the target operating amount, based on the information related to the deflection, and generates the signal related to the target operating amount.

To accurately obtain the shapes of a hoisting load and an object located near the hoisting load, and the height of the ground surface, and present an accurate warning display when the hoisting load approaches the object. A guide information display device is equipped with a data processing unit which: estimates the top surface of a hoisting load, the ground surface, and the top surface of the object, on the basis of a data point group obtained by a laser scanner; generates guide frames representing guide frames that surround the top surface of the hoisting load and the top surface of the object, and also generates height information and height information which represent the elevation of the hoisting load and the object; calculates the distance between the hoisting load and the object on the basis of the estimated top surfaces of the hoisting load and object; and outputs a warning display when the distance is equal to or less than a threshold. The guide information display device is also equipped with a data display unit for displaying guide information obtained by overlapping an image captured by a camera with the guide frames, the height information and the height information, and the warning display which were generated by the data processing unit.

Provided is a crane that is capable of effectively suppressing oscillation related to the pendulum resonance frequency generated in a suspended load on the basis of the suspended length of a wire rope. The crane 1 calculates a suspended load oscillation resonance frequency ωx(n) determined on the basis of the suspended length L(n) of a wire rope (14.Math.16), and generates a control signal C(n) for an actuator according to an arbitrarily defined operation signal, and, on the basis of the resonance frequency ωx(n), generates from the control signal C(n) a filtering control signal Cd(n) for the actuator in which a frequency component in an arbitrarily defined frequency range is attenuated by an arbitrarily defined percentage. The frequency range of the attenuated frequency component and/or the percentage of attenuation is altered on the basis of the suspended length L(n) of the wire rope (14.Math.16).

A control unit performs a travel stop process for stopping travel of a travel unit in response to an indicator detection unit detecting a stop notice indicator section and then detecting a stop position indicator section. After the travel of the travel unit is stopped as a result of the travel stop process, the control unit performs a transfer process for causing a transfer unit to transfer an article. The control unit performs, instead of the transfer process, anomaly notification processing for providing a notification of an occurrence of an anomaly to a superordinate control unit, after the travel of the travel unit is stopped by the travel stop process, in response to: (i) a travel distance, from a position at which the indicator detection unit has detected the stop notice indicator section, being smaller than a determination distance smaller than a notice distance, and (ii) the indicator detection unit detecting the stop position indicator section.
