Sensitivity analysis and optimization of UAV rocket booster launch parameters based on DOE
Aiming at the problem of sensitivity analysis and optimization of UAV rocket booster launch parameters,design of experiment(DOE)based on Taguchi method and response surface method(RSM)was proposed.Firstly,based on Taguchi method,the orthogonal test table was gen-erated,and the response variables such as altitude,velocity,pitch angle and pitch angle velocity when the test booster rocket falling off were simulated and calculated.The sensitivity and importance of each launch parameters were determined through range analysis.Secondly,the regression mathe-matical model was established based on RSM,and the results of multi-objective combination optimi-zation and allowable error boundary prediction of launch parameters were given.Finally,the ration-ality and feasibility of this method was verified by flight test.The proposed method provides some reference for the sensitivity analysis and optimization of UAV rocket booster launch parameters.
