| Summary: | A closed-loop optimal feedback guidance method based on online trajectory optimization and optimal feedback control was proposed for reentry guidance of hypersonic glide vehicle with multi constraints. The mathematical model of the reentry guidance problem with complex multi constraints was established. The reentry guidance strategy which not only can effectively deal with the interior point constraints and decompose the complex terminal constraints but also take online autonomous obstacle avoidance and adapting target change into account was designed. Combining the online trajectory optimization method based on the Radau pseudospectral method and the sequential quadratic programming algorithm with the idea of optimal feedback control based on sample-hold feedback control, the closed-loop optimal feedback guidance method for reentry phase was presented. Numerical simulation results demonstrate that the proposed guidance method shows good autonomous guidance capability and satisfies the real-time requirement for online calculating optimal guidance commands. |
