摘　　要：In this paper,with the use of the moving boundary computational fluid dynamics method,we developed a new real-time optimal control method which can be used to find the optimal flapping mode of a fixed flapping plate.The results show that there is a 54.0%increase in the thrust obtained by the unsteady optimal flapping rule.In addition,to reduce the cost of computation and to have a better understanding of the flapping rule,the maximum velocity at the end tip of the flapping plate is taken as the objective functional,with which the thrust is increased by 22.9%.
