Abstract: The simulation experiments of intelligentized control, the realization of simulation procedure, and the simulation processes of intelligentized control with the theoretical model of fuzzy-neural modular network for ECR ion source of neutron generator are described in great detail. The averaged deviations of computed result of the model in the learning process and the deviation of computed results in the controlling process are reacted changeably with rule number and study rate. The influence of simulation experiment processes of intelligentized control with the correction factor of three different kinds for ECR ion source are researched, and the satisfying results of intelligentized control are obtained through simulation experiments.
