Title:
SELF-ADAPTIVE ITERATIVE GUIDANCE METHOD AND DEVICE FOR AEROSPACE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/095643
Kind Code:
A1
Abstract:
A self-adaptive iterative guidance method and device for an aerospace vehicle. The guidance method comprises the following steps: updating an equivalent specific impulse of an engine in real time according to measurement information of an inertia measurement unit (S1); and adaptively adjusting parameters related to the working state of the engine in an iterative guidance algorithm by utilizing the equivalent specific impulse of the engine updated in real time, to obtain a flight program angle adapted to a thrust descent fault of the engine (S2). According to the guidance method and the guidance device, the adaptive capacity of the iterative guidance algorithm to the thrust descent fault of the engine can be improved, the guidance precision is improved, and the ability of the aerospace vehicle to complete a flight mission under the condition of the thrust descent fault of the engine is improved.
