Abstract

The invention discloses a flight tracking control signal generation device and method based on Hilbert-Huang time grid reconstruction. The flight tracking control signal generation device based on Hilbert-Huang time grid reconstruction consists of a flight altitude tracking error measurement sensor, an aircraft speed measurement sensor, an aircraft flight path angle measurement sensor, an aircraftparameter and tracking state input unit, an aircraft central control MCU (Microcontroller Unit), a flight state display unit and a controller unit. In the flight process of an aircraft, the flight altitude tracking error measurement sensor, the speed measurement sensor, the flight path angle measurement sensor and the central control MCU are started to measure and display the current flight altitude tracking error, the speed and the flight path angle states in real time; the central control MCU of the aircraft automatically executes an internal Hilbert-Huang time grid reconstruction dynamic optimization algorithm according to a state tracking instruction sent by an air traffic control mechanism, and an optimal control strategy for enabling the aircraft to reach a specified tracking statein a shortest time is obtained; and the obtained optimal control strategy is converted into a control signal to be sent to a control signal output unit.
