Finite Thrust Orbit Interception Optimization Using Hybrid Genetic Algorithm

The finite thrust orbit interception optimization of space-based KKV was considered.With the velocity gain guidance law as orbital transfer scheme,mathematical model was established.Hybrid genetic algorithm was proposed by introducing complex algorithm into conventional genetic algorithm,which was utilized to optimize orbit interception of the interceptor.Integration objectives were the weighted sum of minimum fuel consumption,minimum intercept time and minimum miss distance.Through the simulation which used space-based KKV in Sun-Synchronous orbits to intercept target points in GPS-orbits,optimization performance of HGA was analysed.Simulations validated that HGA could availably solve this complex nonlinear multi-object optimization.Furthermore,local search capacity was enhanced as well as calculational efficiency was improved.
