Abstract
The exemplary embodiments are directed to a control system and method of predicting how a machine will respond to occasional or periodic maintenance or service, and adjusting the machine accordingly to account for the change in machine behavior due to the maintenance or service action. More specifically, in a machine under closed-loop control subject to occasional maintenance or service, the maintenance or service results in transient in machine performance. To mitigate transients in machine performance due to maintenance or service, a prediction of the maintenance or service effect is fed forward the existing control system just prior to the occurrence of maintenance or service in order to compensate for the maintenance or service effect. This prediction is continually updated and refined using subsequent measurements of the effect of maintenance or service on machine performance.
