Part Number: DRV8312-69M-KIT
Other Parts Discussed in Thread: CONTROLSUITE
Currently we are trying to verify Level 5 (Trapezoidal Control of BLDC Motors Using Hall Effect Sensors).
While building Level 5 we are getting compilation error as below. MATH_TYPE is set as IQ_MATH.
With respect to 1st link above, we changed the settings as in the attached snap, but the issue related to ISA error is still there. (when MATH_TYPE = IQ_MATH)
Secondly, we want to understand, why BLDC_Sensored-Settings.h shall have only FLOAT_MATH? [why IQ_MATH can not be used?]
How MATH_TYPE affects performance of Level 5 or Level 6?
For now, we changed the pid_grando.f file as below and Level 5 started working then. [bypassing _IQsat()] and MATH_TYPE = FLOAT_MATH
/*v.term.Out= _IQsat(v.data.v1, v.param.Umax, v.param.Umin); */ \
if (v.data.v1 > v.param.Umax) \
v.term.Out = v.param.Umax; \
if (v.data.v1 < v.param.Umin) \
v.term.Out = v.param.Umin; \
v.data.w1 = (v.term.Out == v.data.v1) ? _IQ(1.0) : _IQ(0.0); \
