An operation condition setting support device supporting setting of an operation condition of a plant includes a state value acquirer acquiring state values representing states of controlled devices during operation of the controlled devices, a predictor estimating predicted values for the respective state values at a predetermined future time point based on the respective state values acquired by the state value acquirer, and a notifier, in a case where an index calculated based on a difference between each of the state values at the predetermined time point acquired by the state value acquirer and each of the predicted values at the predetermined time point or a later time point than the predetermined time point estimated by the predictor or a change ratio of the difference satisfies a predetermined condition, providing notification of the case.
PREDICTIVE MODELLING AND CONTROL FOR WATER RESOURCE INFRASTRUCTURE
A control mechanism scheduler for a water resource infrastructure receives operating data and disturbance data, the operating data describing infrastructure components of the water resource infrastructure, the disturbance data comprising a disturbance signal describing a disturbance expected to disturb the water resource infrastructure. The control mechanism scheduler generates classes for disturbance signals, generates simulations of the water resource infrastructure, and generates schedules of setpoints for control mechanisms actuable to control the infrastructure components of the water resource infrastructure in accordance with approaching a predetermined objective.
DYNAMICS MODEL FOR GLOBALLY STABLE MODELING OF SYSTEM DYNAMICS
A system and computer-implemented method are provided for training a dynamics model to learn the dynamics of a physical system. The dynamics model may be learned to be able to infer a future state of the physical system and/or its environment based on a current state of the physical system and/or its environment. The learned dynamics model is inherently globally stable. Instead of learning a dynamics model and attempting to separately verify its stability, the learnable dynamics model comprises a learnable Lyapunov function which is jointly learned together with the nominal dynamics of the physical system. The learned dynamics model is highly suitable for real-life applications in which a physical system may assume a state which was unseen during training as the learned dynamics model is inherently globally stable.
