Question asked by Peter Kostadinov on Apr 23, 2019



I'm using reference solution from MCRSP_PMSM_V1.2.0 package.

For my project it is necessary smoothly to be switched between open to closed loop and vice-versa during the rotor is spinning. The idea is when the speed is low and bemf is too small to be used to determine the rotor's position to switch in open loop mode and position of the rotor to be determined similarly to start-up mode. When the speed is raised enough, then to switch in closed loop again and the position of the rotor to be determined by the bemf.


Best Regards,
