Simulation of Working Pattern Discrimination Method in Satellite Power Balance Model
摘要
Abstract
Satellite power balance model is used to calculate power consumption to make sure that satellite power can support the execution of tasks. It requires to discriminate satellite working pattern before calculating power consumption. The accuracy of pattern discrimination will influence the results of power consumption directly. However, there is no universal model to realize this function for multitasking satellite, especially when satellite attitude will change with tasks. In light of this, a method based on concordance list and database access to get working pattern is proposed. The concordance list of working status in each time sequence and satellite working pattern is established at first and then we inject time sequence data into a database. The working pattern in concordance list can be obtained after selecting working status from the database. In order to improve operating efficiency, accelerating algorithm is utilized in this method to decrease running time. Acceleration parameters are discussed through simulation. This method is suitable for multitask satellite that can be constrained by time series.关键词
