摘 要：提出了一种基于遗传算法在线参数辨识的模糊内模控制，并将其应用于过热器的温度对象，构成针对大时延变参数对象的智能控制系统；用遗传算法在线得到对象模型参数的估计值，并将参数估计值送至模糊内模控制器作为补偿，提高了控制系统的鲁棒性。仿真结果证明了该控制系统的可行性和有效性。

Abstract: A FIMC of online identification based on GA was proposed, which was mainly used to deal with large timedelay and timevarying processes, forming the intelligenct control system. Using GA, estimate parameters of the processes model were obtained on line, and these parameters were been sent to fuzzy internal model controller for accurate compensation. The robustness of control system was improued. The simulation results show that the method is feasible and effecbive.
Key words: intelligent control; fuzzy internal model control; genetic algorithm; online identification
