Abstract:
1. A method for synchronizing a second process to a first process, wherein state data regarding input to and output of a model of the first process is available to the second process after a delay period, the method comprising: beginning a data collection period; receiving delayed state data points regarding the input to and output of the model by a controller of the second process; storing the delayed state data points received during the data collection period; ending the data collection period after receiving and storing delayed state data that represents the state of the input to and output of the model at a point in time after the beginning of the data collection period; determining a current state of the model of the process based on at least some of the stored state data points and predetermined information regarding a behavior of the state of the model; and setting a current state of the second process according to the determined current state of the model, thereby synchronizing the second process to the first process.
