Title:
HIGH-PRECISION ANGULAR VELOCITY CONTROL METHOD UNDER SHORT-TIME LARGE-BOUNDARY INTERFERENCE
Document Type and Number:
WIPO Patent Application WO/2022/127313
Kind Code:
A1
Abstract:
The present invention discloses a high-precision angular velocity control method under short-time large-boundary interference. Orbital control information is brought into a posture control system by performing deep coupling analysis with a guidance system, and control schemes are respectively designed for two typical control working conditions: orbital control startup and orbital control shutdown, thereby satisfying the requirements of a detection system while ensuring the stability of a detector. The high-precision angular velocity control method under short-time large-boundary interference provided in the present invention achieves the purpose of rapidly reducing the angular velocity by means of advanced control when an orbital control engine is started, and when the orbital control engine does not work, the system damping is increased by means of pseudo-rate feedback control, so as to control the angular velocity at a low level. The present invention solves the problems existing in the prior art that a short-time large-boundary structure interference leads to rapid increase of the angular velocity of the detector, resulting in loos of lock of the detection system, and the excessively sufficient control capability of the posture control engine makes it difficult for the angular velocity limit ring to satisfy the requirements of the detection system. The present invention is simple and reliable, and is easy to implement in engineering.
