Claim 1:
2. The plant operating condition setting support system according to claim 1, further comprising:
a learning device that performs the deep reinforcement learning, wherein
the learning device includes:
an action determination circuit that acquires a plurality of measured values indicating states of the plurality of controlled devices and outputs a plurality of PID parameter used by each of the plurality of control devices; and
a valuation function circuit that calculates a valuation of a set of i) a plurality of measured values indicating states of the plurality of controlled devices occurring when the plurality of control devices control the plurality of controlled devices by using the PID parameter output by the action determination circuit and ii) the PID parameter used, wherein
the valuation function circuit is learned in such a manner as to reduce an error between i) an expected value of a reward value that would be obtained when the control device adjustment parameter determination circuit determines the PID parameter that are input to the controlled devices while the plurality of controlled devices are in the states indicated by the plurality of measured values, the manipulation variables for control determined by the plurality of control devices by using the PID parameter determined are input to the plurality of controlled devices to update the states of the plurality of controlled devices, and optimum PID parameter continue to be selected afterwards, and ii) a valuation calculated by the valuation function circuit.
