A processing unit is coupled to the control system and configured to estimate a production disturbance and a feed consistency disturbance of the refiner based on the plurality of operation conditions. The system also includes a second control system coupled to the processing unit and configured to generate a target operating condition based on the production disturbance and the feed consistency disturbance. The first control system is further configured to control an operation of the refiner based on the target operating condition.
