sensorless control pmsm motor using tms320f28335 dsp

Hi,

 I am working on sensorless control of pmsm motor using tms320f28335 dsp chip. I wrote  " C " code for sensorless control of pmsm motor using sliding mode observer for estimating rotor flux angle, there by estimate the speed. But when I am trying to run the program I am getting one software error.

" /* Initialize the SMOPOS constant module*/

     smo1_const.Rs = _IQ(smo1_const.Rs);

     smo1_const.Ls = _IQ(smo1_const.Ls);

     smo1_const.Ib = _IQ(BASE_CURRENT);

     smo1_const.Vb = _IQ(BASE_VOLTAGE);

     smo1_const.Ts = _IQ(T);

     SMO_CONST_MACRO(smo1_const);    "

Above mentioned is the code and the error is :

error: expected a field name

The error is same for all the lines. I already assigned the value of "Rs" and "Ls" values initially. I don't know why I am getting this error.

Could you please  suggest me how to overcome the above error.

Thanks in advance.

Best Regards,

Suneel
