摘要： An object of this invention is to provide a plant operation support-system server and a plant operation support system which can manage the current situation of overall resources that are required for performing jobs corresponding to a procedure manual, and can further achieve resource management with enough margin based on future prediction. Using a current procedure-manual location determination unit, a control unit of a plant operation support-system server determines a current location in procedure-manual data DM, based on a condition of the plant acquired through sensors by a plant data acquisition unit. When there is a change in the current location, the control unit causes a current-situation management determination unit to assign currently-required resources according to the current position and causes a predictive management determination unit to predict presence/absence of resource deficiency.

摘要： A control system is configured to operate a plant to achieve an optimal value for a performance variable of the plant. The system comprise a feedforward controller configured to receive a measurable disturbance to the plant and generate a feedforward contribution to a control input to the plant using the measurable disturbance. The system also comprises an extremum-seeking controller configured to receive the performance variable from the plant and generate an extremum-seeking contribution to the control input to drive the performance variable to the optimal value. The system further comprises a control input element configured to generate the control input by combining the extremum-seeking contribution and the feedforward contribution and provide the control input to the plant.

摘要： A circuit and method for controlling a rotating or oscillating element of a DC motor, including a positional deviation correction signal generator in addition to a position sensor which detects an amount of rotation or oscillation and position of the rotating or oscillating element, a main control circuit that includes a DC motor driving circuit, and a computer which controls the main control circuit. The output signal of the positional deviation correction signal generator is controlled by the computer based upon positional deviation correction information and signals from the position sensor, so that the positional deviation correction signal generator compensates for any positional deviation of the rotating or oscillating element of the DC motor at a stopping position thereof.

摘要： An evaluation value prediction unit predicts an evaluation value at a time point after a given time passes from a predetermined evaluation time based on input data related to an operation of a factory at the evaluation time using a learned prediction model. The prediction model is a learned model that is learned so that the evaluation value related to the operation of the factory at a time point after the given time passes from one time point is output by inputting a plurality of kinds of data related to the operation of the factory at one time point. An evaluation value output unit outputs information related to the evaluation value.
