Title:
CONTROL METHOD AND APPARATUS FOR WORK MACHINE, AND WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/020129
Kind Code:
A1
Abstract:
Provided in the present application are a control method and apparatus for a work machine, and a work machine. The method comprises: acquiring the current work state of a work machine; determining the current decision-making behavior of the work machine on the basis of the current work state and a state behavior decision-making model; and controlling the work machine to perform construction work on the basis of a control signal corresponding to the current decision-making behavior. The state behavior decision-making model is obtained by means of training on the basis of a sample work state of the work machine, a sample decision-making behavior and a reward value corresponding to the sample decision-making behavior. The reward value is determined on the basis of an actual position curve and a target position curve of a work part in the work machine. The actual position curve is determined on the basis of the sample decision-making behavior. By means of the method and apparatus and the work machine provided in the present application, the debugging workload of an engineer is reduced, the debugging time is shortened, the debugging cost is decreased, and the intelligent construction level of a work machine is raised.
