摘要：

A predictive controller is used to assess the advantage of combining feedforward and feedback actions for the control of a simulated flotation process. Results show that the feedforward action reduces the effect of flotation feed grade and flowrate variations and improves the performance of the traditional feedback loop. Some simulation runs also demonstrate that an inadequately tuned feedback compensation can deteriorate the action of a well-tuned feedforward controller. (C) 2000 Elsevier Science S.A.
