This paper mainly introduces a flare control law design of a civil aircraft. The characteristic of auto landing was analyzed in this paper. The flare controller was designed based on the PID method which consists of two loops. The outer-loop generates a vertical speed command based on both the initialization flare altitude and the ground speed. The inner-loop is a vertical speed controller, which tracks the vertical speed command. The simulation results show that the flare control law has high precision and satisfy the vertical speed requirement when touch down.

摘要

This paper mainly introduces a flare control law design of a civil aircraft. The characteristic of auto landing was analyzed in this paper. The flare controller was designed based on the PID method which consists of two loops. The outer-loop generates a vertical speed command based on both the initialization flare altitude and the ground speed. The inner-loop is a vertical speed controller, which tracks the vertical speed command. The simulation results show that the flare control law has high precision and satisfy the vertical speed requirement when touch down.
