【Abstract】 Based on the feedback mechanism of the biologic immune system a compound control method that the conventional PI controller is combined with an immune controller is presented. In the concrete the immune controller is in series with the PI controller whose parameters have been optimized. The output of the PI controller is reprocessed by an immune controller. Considering the practical system, an error reference function used to limit the overshoot is presented also. And the method to adjust and determine the parameters of the controller system is introduced. The results of the imitation experiments show that the method of the compound control can be used to improve the control performance of the system temperature for MOCVD effectively.更多还原
