In the iron ore sintering process，to optimize two key parameters，the burning through points and the bunker-level，an multi-objective optimal control method is presented based on fuzzy satisfactory degree.First，an intelligent optimal control model of the burning through points is established by using fuzzy control，predictive control and switching control strategy.Next，an expert control model is designed for the bunker-lever.Finally，the satisfactory-degree function of the system is designed to obtain satisfactory solutions，which transforms the multi-objective optimization problems into the single-objective optimization problems and eventually results in multi-objective control of the sintering process.Results of simulation and actual runs show that the proposed method is feasible and effective.
