TADANO LTD.

This control system for controlling an actuator of a crane is provided with a signal processing unit for generating a signal related to a target operating amount of the actuator, a feedback control unit for controlling the actuator on the basis of the difference between the signal relating to the target operating amount, and a fed-back signal relating to the operating amount of the actuator, and a feed-forward control unit which controls the actuator on the basis of the signal relating to the target operating amount, in cooperation with the feedback control unit, and learns the characteristics of the actuator by adjusting a weighting factor on the basis of a teaching signal, wherein the signal processing unit converts an input signal into the signal relating to the target operating amount by removing a pulse-shaped component from the input signal.

A performance information server comprises: a request acquisition unit that acquires a request including machine-type information for a work machine, and a performance information request to indicate performance information for the work machine; a storage unit that stores specification data for the work machine in association with the type of the work machine; a control unit that acquires the machine type information included in the request and the performance information for the work machine, on the basis of the specification data corresponding to the machine type information; and a response presentation unit that presents a response including the performance information acquired by the control unit.

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.

An operation assistance module operates in coordination with an operation control unit that controls the actions of a work machine, or with an operation control unit of an image generation application that controls the actions of an image of the work machine displayed on a display unit, wherein the operation assistance module has: a request issuance unit that transmits, to a performance information server, a request including machine type information for a work machine and a performance information request to indicate performance information for the work machine; a response acquisition unit that receives from the performance information server a response including the requested performance information; and an operation assistance unit that reflects the acquired performance information in the control of the operation control unit.
