SIDPAC和LSPID的算法研究及对比分析

对国外具有代表性的Vladislav Klein 的参数辨识算法SIDPAC和试飞院使用多年的辨识程序LSPID进行分析研究,指出其中的不同之处,利用二者分别在NASA Twin Otter和中国某历史型号上原有的部分计算结果,进行了大量的研究和计算,对比验证分析,最后确认上述两程序具有较好的一致性和工程实用价值,为以后的工程工作创造了更好的条件.

Algorithm Research and Contrastive Analysis of SIDPAC and LSPID

This paper does the research on klein′s parameter identification algorithm SIDPAC from abroad and LSPID used many years in CFTE,and point out the differences.Based on original results of NASA Twin Otter and a Chinese history model respectively through SIDPAC and LSPID,this paper does a lot of research and calculation.Through the comparision and analysis verification of the computation results,it′s confirmed that two algorithms have good consistency and practical value in engineering.The study creates better condition for future project work.
