ROBUST OPTIMAL BALLISTIC TRAJECTORY DESIGN BASED ON GENETIC ALGORITHM AND MIN-MAX METHOD
A robust optimal trajectory design method was proposed. The optimal terminal attack performance can be assured through the integrated optimization of the whole trajectory with Genetic Algorithm (GA), The strong robustness of the trajectory to the disturbances can be assured by integrating min-max method into the GA optimization process. The paper firstly gave the detailed design steps, took the short-range anti-tank homing missile as an example to give the optimization mathematical model, and then designed its robust optimal trajectory and had a simulation. Simulation results showed that the correctness and effectiveness of the robust optimal trajectory design method. The robust optimal trajectory could make the short-range anti-tank homing missile attack the top of the target accurately with maximum impact angle under various constraints and disturbances. The design process avoided the trouble of try-and-test and reduced the design time. The method can be easily realized in the actual flight system.
