1. A method comprising:
receiving, via one or more processors, one or more process inputs and one or more process outputs associated with one or more operations of one or more components of an industrial automation system;
determining, via the one or more processors, a model representative of the one or more components based on the one or more process inputs and the one or more process outputs;
identifying, via the one or more processors, a boundary response time threshold associated with an unmeasured operating parameter of the one or more components based on the one or more process outputs;
determining, via the one or more processors, one or more inputs to modify the one or more operations of the one or more components based on the boundary response time threshold;
providing, via the one or more processors, the one or more inputs to the model;
receiving, via the one or more processors, one or more measured outputs of the one or more components after providing the one or more inputs to the model, wherein the one or more measured outputs are acquired a time period below the boundary response time threshold;
receiving, via the one or more processors, one or more predicted outputs from the model based on the one or more inputs;
determining, via the one or more processors, the unmeasured operating parameter based on a state estimator configured to employ the one or more predicted outputs and the one or more measured outputs to determine the unmeasured operating parameter; and
adjusting, via the one or more processors, an electrical power provided to one or more motors associated with the one or more components based on the unmeasured operating parameter.
