Optimal control strategy of throttle diameters fitted for airplane pressure fueling system

The pipeline model of airplane pressure fueling system is analyzed in this paper, the pipelines that connect to each reservoir should be reconstructed, and the appropriate throttle devices are desired to set for the control of pipe flows. According to the different types of predetermined fueling schemes, the Refine Genetic Algorithm is presented to optimize throttle diameters, the constraints of fueling time disparity and maximum pulsating pressure are considered also, then the method is implemented with the help of Matlab software, the satisfied fueling time and maximum pulsating pressure are obtained. At last the experimental results show that the optimal strategy mentioned above is valid and feasible.
