CPC G05B 13/048 (2013.01) | 18 Claims |
1. A controller for an energy plant, the controller comprising:
a data collector coupled to a device of the energy plant, the data collector configured to:
obtain a time series of a performance variable associated with the device;
obtain an auto-correlation function data of the device based on the time series of the performance variable associated with the device;
obtain a partial auto-correlation function data of the device based on at least one of the time series of the performance variable or the auto-correlation function data, the partial auto-correlation function data excluding a contribution of a portion of the samples considered in the auto-correlation function;
a model generator coupled to the data collector, the model generator configured to generate an electronic model of the device using both the auto-correlation function data and the partial auto-correlation function data to select parameters of the electronic model and modify the parameters of the electronic model until the parameters are statistically significant and a slope of the auto-correlation function data or the partial auto-correlation function data satisfies a threshold criterion; and
a predictor coupled to the data collector, the predictor configured to predict a first time, at which a future event of the device is predicted to occur, based on the electronic model.
