Abstract EN
Rotor position detection is a prerequisite for achieving good control performance of PMSM.
For a PMSM control system based on an optical encoder, it is a difficulty to detect rotor position and achieve R-Signal zero-setting.
To solve the problem, a hybrid optical encoder is used in the paper by which a scheme for rotor position detection and R-Signal zero-setting is proposed.
This encoder can do absolute and incremental rotor position detection simultaneously; here, the former is used for acquiring imprecise rotor position and the latter is for precise rotor position.
Firstly, two detection methods of the encoder are analyzed, and a scheme for rotor position detection is proposed: absolute rotor position is used for motor starting before achieving R-Signal zero-setting; once achieving R-Signal zero-setting, incremental rotor position detection that has high precision is adopted.
Then a novel scheme for R-Signal zero-setting is emphatically proposed.
Finally, the simulation is conducted.
Results show that rotor position detection and R-Signal zero-setting can be achieved by the proposed scheme.
