TMS320F28335: esmo中数据溢出问题

Part Number: TMS320F28335


TI工程师,及各位工程师们好;

最近我在自己逆变器平台开发永磁同步电机无位置传感器算法,将计算得到的Iα,Iβ,Uα,Uβ送入开源smo模块能得到估计角度,但程序移植esmo算法后,按照给定例程将同样的Iα,Iβ,Uα,Uβ以及runspeed、cmdspeed送入esmo中观测角度始终是-IQ(0.5),将运行变量调出来查看后,发现IαlphaError和IbetaError出现数据溢出为_IQ(127.5),Zαlpha、Zbeta和kslf始终是0。IF开环运行速度上去后仍然是这种情况,请问这是哪里出了问题?
