ACCURACY-OPTIMAL CONTROL DECISIONS FOR SYSTEMS

摘要

Methods, systems, and apparatuses are provided for controlling an environmental maintenance system that includes a plurality of sensors and a plurality of actuators. The operation levels of the actuators can be determined by optimizing a penalty function. As part of the penalty function, the sensor values can be compared to reference values. The optimized values of the operation levels can account for energy use of actuators at various operation levels and predicted differences of the sensor values relative to the reference values at various operation levels. The predicted difference can be determined using a transfer model. An accuracy of the transfer model can be determined by comparing predicted values to measured values. This accuracy can be used in determining new operational levels from an output of the transfer model (e.g., attenuating the output of the transfer model based on the accuracy).

1. A method of controlling an environmental maintenance system that includes a plurality of actuators and a plurality of sensors, each sensor measuring a value of a physical condition of an environment, the method comprising:
receiving sensor values S corresponding to the sensors, the sensor values S corresponding to operational levels U1 of the actuators; receiving new operational levels U2 of the actuators, where U2−U1=dU; predicting a change dS in the sensor values S, the change dS corresponding to the change dU, wherein the prediction is performed in accordance with a transfer model; operating the actuators with the new operational levels U2; subsequently, measuring new sensor values Snew; repeating the receiving, prediction, operation, and subsequent measurement at a plurality of times; determining a metric of an accuracy of the transfer model by comparing the predicted sensor values to the measured sensor values; receiving a proposed change to the operation levels of the actuators, the proposed change being based on the transfer model; based on the accuracy metric, adjusting the proposed change to the operation levels of the actuators; and setting the operation levels of the actuators based on the adjustment to the proposed change.
