Abstract: An automation system for a drilling rig includes a processor and a computer memory in communication with the processor and storing computer executable instructions, that when implemented by the processor cause the processor to perform functions that include receiving as a function of time at least one of a) at least one surface operating parameter and b) at least one downhole operating parameter. The processor further may at least one of filter and smooth the at least one surface operating parameter and the at least one downhole operating parameter to generate processed data. The processor may generate a measure of drilling energy from the processed data and determine a minimum of the measure of the drilling energy, and calculate a target value of the at least one of the at least one surface operating parameter and the at least one downhole operating parameter.
