I have to control the position of platform connected to a shaft of brushless dc motor. 1 degree of accuracy is required i.e. i should be able to move the platform from 60 degree position to 61 degree.
I have gone through many papers but all of them are on speed control or torque control.
Some questions:
Can i use vector control method for BLDC motors with trapezoidal back-emf? If yes, how do I get d-q axis parameters (Lq, Rq etc.)? If no, what is the other method which can be used?
In Mathematical model of BLDC motor what all parameters are necessary to be considered and what can be ignored?
Basically how to position the shaft so accurately?
