基于免疫反馈机理的温度自动控制研究

基于生物免疫系统的反馈机理，提出了一种用免疫控制器与传统PI控制器相结合的复合控制方法，印将传统PJ控制器与免疫控制器相“串联”，在传统PI控制器参数已经优化的情况下，用免疫控制器对其输出进行“再处理”．并针对实际系统提出了一种限制超调量的误差参数函数，介绍了控制系统参数整定的方法．仿真和实验表明，这种复合控制的方法能有效地改善金属有机化合物化学气相淀积系统温度的控制性能．

The research on temperature autocontrol based on the immune feedback mechanism

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.
