摘要: 卫星控制系统具有强非线性、系统参数大范围剧烈变化、存在严重不确定性和工作环境恶劣等特点,而传统的定性方法或者定量方法均难以取得满意的故障诊断效果,从寻求定性/定量方法结合的新机制出发,提出了采用定性仿真和奇偶空间法相结合的定性/定量混合建模新方法,并利用了模糊逻辑,较好地实现了定性/定量知识的有机结合。定性/定量混合模型可充分利用系统的信息,实现对卫星控制系统的有效、准确、快速地故障诊断,仿真结果验证了该方法的有效性。

Abstract: Based on conquering the shortcomings of conventional qualitative or quantitative fault diagnosis methods for the satellites control system and seeking the new mechanism of combining the qualitative and quantitative method,a new mixed modeling method with the qualitative simulation (QSIM) and the parity space method is proposed. The method achieves the organic combination of the qualitative and quantitative information based on the fuzzy logic. The qualitative/quantitative hybrid model can integrate the system information comprehensively ,and then realize the efficient, accurate and rapid fault diagnosis for the satellite control system. Simulation experiments show that the method is efficient and feasible.

Key words: satellite control system, fault diagnosis, the qualitative/quantitative mixed model, qualitative simulation, parity space
