Semi-physical simulation method and system

Abstract

The embodiment of the invention discloses a semi-physical simulation method and system. The method comprises the steps that: a non-standard sphere infrared radiation simulation module receives a flight parameter transmitted by a simulation calculation module, wherein the flight parameter is generated through the calculation of the simulation calculation module according to a control instruction ofa satellite-borne calculation module; non-standard sphere infrared radiation simulation information is generated through calculation according to the flight parameter; and the non-standard sphere infrared radiation simulation information is sent to an infrared earth sensitive module, so that the infrared earth sensitive module generates measurement information and sends the measurement information to the satellite-borne calculation module. The problem that infrared radiation characteristic simulation precision is not high when a simplified standard sphere is adopted is solved; high-precisioninfrared radiation characteristic simulation is achieved; and the verification capacity of an attitude control system is improved.

technical field [0001] The embodiments of the present application relate to the technical field of simulation, and in particular to a half-physical simulation method and system. Background technique [0002] During the in-orbit operation phase of the satellite platform, the earth sensor is usually used to detect the infrared radiation energy of the earth, combined with the calculation of the orbital height, to obtain the pitch angle and roll angle of the platform relative to the local vertical line of the earth. The closed-loop verification of various functions and performances of the earth sensor is one of the key tasks of the hardware-in-the-loop simulation system. During the semi-physical simulation test of the satellite ground test, the earth simulator is used to simulate the infrared radiation characteristics of the earth according to the different orbital heights and attitude information of the satellite platform, and provide light excitation information for the earth ...
