| 英文摘要 |
| This paper investigates the problem of impact time control guidance of flight vehicle intercepting maneu
vering target, an adaptive impact time control guidance law is proposed with prescribed performance. Considering the
influence of the convergence time on the hitting time accuracy of the impact time control guidance law, the paper presents
a performance envelope function with fixed time convergence. A prescribed performance guidance law is proposed with
f
ixed-time convergence. The relationship between the selection of the performance function parameters and the variation
of initial acceleration is analyzed. By setting the parameters of the performance function, the transient and steady-state
performance of the impact time error can be adjusted in combination with the maneuvering capability of the flight vehicle,
and the impact time error can converge into the performance function envelope prior to the impact time command. The
simulation results are presented to validate the effectiveness and correctness of the proposed guidance method. |
