Title:
PLANT CONTROL SYSTEM AND PLANT CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/084784
Kind Code:
A1
Abstract:
Provided is a control system capable of outputting an operation amount that quickly converges the controlled amount to a target value while suppressing oscillation of the operation amount. This plant control system is characterized by comprising a learning processing device that determines an optimal action of a plant through learning and a control processing device that controls the plant according to the optimal action determined by the learning processing device, said learning processing device being provided with: a state information control unit that converts a plurality of plant signals into plant states and defines a target state; an action value update unit that uses a state, action, and target state of the plant to determine an action value, which is the value of the state and action between the last operation and the current operation; and an optimal action selection unit that uses the action value to determine an optimal action for achieving the target state, wherein an action that suppresses oscillation of an operation amount of the plant is determined as the optimal action.
