| Abstract: | In this paper,the optimization model for multi-stage solid rocket is established,and a new hybrid optimization method combined with sequential unconstrained minimization technique(SUMT),genetic algorithm(GA) and Powell is proposed.Based on Visual C++ and GA toolbox in MATLAB,the method is adopted for SSO trajectory optimization.The simulation results demonstrate that when dealing with those optimization problems the method is better than any other optimization algorithm in computing speed and accuracy. |
