The invention discloses an active anti-interference internal model control system and control method, belongs to the technical field of industrial process control, introduces an active anti-interference control mode into traditional internal model control, and designs a specific structure of an interference suppressor model to meet the requirements of anti-interference performance and robustness of the system. The active suppression function of external interference is realized, the capability of the control system for processing large-time-delay objects is enhanced, and the robustness and anti-interference performance of the control system are improved. On the premise of the balance relation between the dynamic performance and robustness of the system, balance setting of parameters of the controller is achieved; the stability of the control system is controlled during model matching and model mismatching, and it is indicated that the method still has good dynamic characteristics and good robustness under the
