Other Parts Discussed in Thread: CONTROLSUITE
We are designing bldc motor controller using TMS320F28031. When we are testing on vehicle (battery operated) we are observing jerking at initial starting condition and once vehicle is moving it was smooth. i tried to find the issue and observed that at the start hall signals are coming in a reverse sequence for 10-12 states. it means that at the start vehicle is moving in the reverse direction and software is trying to commutate it in forward direction and due to that wrong commutation is happening and jerking sound coming.
Please suggest that what type of precautions we need to take for starting conditions and also suggest us the theory for this type of applications.
