Problems solved by technology

If the traditional semi-physical simulation method is used, and the sun altitude angle needs to be changed from -90 degrees to 90 degrees, under the condition that the above conditions are met, the entire simulation process generally takes several months, which is very expensive in terms of time and labor costs. unacceptable and unnecessary

Abstract

The invention relates to a semi-physical high-speed simulation method based on the smooth switching of a state. The method comprises the following steps: S1: according to a purpose of simulation verification, selecting a physical quantity to be revised; S2: judging whether the physical quantity to be revised is a dynamics integration variable or not, if the physical quantity to be revised is the dynamics integration variable, executing S4, and otherwise, executing S3; S3: converting the physical quantity to be revised into a corresponding dynamics integration variable; and S4: through switching control in a certain time range, revising the dynamics integration variable to finish the smooth switching of the state in a semi-physical simulation process. By use of the semi-physical high-speed simulation method, in a semi-physical simulation switching process, real-time / super real-time seamless connection is realized, dynamics continuity is guaranteed, and two states before and after switching are in smooth transition.

Description

technical field [0001] The present invention relates to a satellite semi-physical fast simulation method, specifically a semi-physical fast simulation method based on state smooth switching, and relates to dynamics in a semi-physical simulation system switching from one real-time simulation state to another new one Real-time simulation state, and continue to run in the new state, and switching between these two simulation states will not cause unexpected sudden changes in the state of the entire semi-physical simulation system. Background technique [0002] For some inclined orbits, the solar elevation angle can vary from -90 degrees to 90 degrees. When the sun altitude angle is in different angle intervals, the satellite control scheme is also different. In order to check the control scheme of the satellite in each sun altitude angle interval and whether the switching process of the control scheme is correct, it is necessary to verify the design scheme by means of semi-phys...
