| Abstract: | In allusion to sensorless control problems of permanent magnet synchronous motors,a kind of sliding-mode observer(SMO) was designed to estimate motor rotor position and speed.The SMO adopted adjustable parameters of sigmoid function as the switch function to carry out continuous control,so that the oscillation of system was weakened effectively,the system structure improved.The SMO against the parameter variation and the uncertainties is of good robustness. |
