One of the most important performance indexes , which affect the industrial application of amb , is the dynamic rigidity , because the dynamic rigidity of the system , which uses the classical pid controller , is too small , we improve the pid controller . at last , we realize the optimal controller by using the digital signal processor chip ( tms320f240 ) 影響磁軸承應(yīng)用的很重要的一個(gè)性能指標(biāo)就是動(dòng)態(tài)剛度,針對對傳統(tǒng)的pid控制器控制下的動(dòng)態(tài)剛度太小的問題,對pid控制器進(jìn)行了改進(jìn),提高了在pid控制下磁軸承系統(tǒng)的動(dòng)態(tài)剛度。
The research result indicated : for the strip primary mirror discussed in this article , the hexagon light - weighted cell has the best structural rigidity quality , the square cell is a little worse , the triangle cell is the worst ; there is an optimum on primary mirror thickness ; on condition of 1g gravity load combining with 4 centigrade uniform temperature rising , the thinner and higher of the flexible support reed , the better of the primary mirror surface figure . the decision of the structural parameters of the flexible support reed must take static rigidity , dynamic rigidity , static strength and dynamic strength of primary mirror assembly into account 研究結(jié)果表明:對于本文的長圓形主鏡,采用正六邊形輕量化孔,鏡體結(jié)構(gòu)剛性品質(zhì)最好,正方形次之,正三角形最差;主鏡鏡體厚度存在最佳值;主鏡組件在1g重力、均勻溫升4共同作用的工況下,主鏡柔性支撐簧片厚度越小、高度越高,主鏡綜合面形誤差( p - v值)越小,但同時(shí)主鏡組件的剛體位移增大、固有頻率下降,因此柔性支承結(jié)構(gòu)參數(shù)的確定要綜合考慮主鏡的綜合面形誤差和主鏡組件靜態(tài)剛度、動(dòng)態(tài)剛度、靜態(tài)強(qiáng)度和動(dòng)態(tài)強(qiáng)度等因素。
