Abstract:
For realizing vector control on the double-rotor-machine,it is necessary to acquire the relative angular speed / position between the inner rotor and the outer rotor. A method for measuring the relative
angular speed / position based on resolvers was put forward. Firstly,based on the transformation of coor-dinates,the all-digital R2D algorithm was improved to close-loop track the relative angular speed / position between two different rotors while the complexity of the algorithm is not increased,which made the con-verter easily realized. Secondly,simulation was done to prove the correctness of this algorithm,and then a measure system was designed based on TMS320F2812,including its hardware and software. Finally, experiment was finished to prove the reliability of this system.
