Nonlinear online optimal guidance method of interceptor missile midcourse guidance
For the problem of nonlinear optimal guidance solution of interceptor missiles,a closed-loop online optimal guidance method suitable for interceptor missile midcourse guidance was pro-posed based on the basic theory of linear Gauss pseudos pectral method.Firstly,THAAD interceptor missile was modeled,and the mathematical model of the optimal guidance problem in the midcourse guidance of interceptor missiles was established,and then the proposed method was used to solve the problem.Finally,three examples were set to simulate and verify the adaptability and computational performance of the method.The simulation results show that the solution result of the proposed meth-od is very close to the nonlinear optimal solution,and has higher solving efficiency,which meets the needs of online application.
