Abstract
A position sensorless method for direct torque control with space vector modulation (DTC-SVM) of hybrid excitation flux-switching generator (HEFS) is presented. Based on the synchronous angular frequency acquired by a m-order low-pass filter, a programmable first-order low-pass filter together with a band pass filter and a coordinate transformation is used to estimate the stator flux-linkages without magnitude and phase angle errors. Thus, the instantaneous torque and the rotor position can be accurately estimated based on the precise stator flux-linkages. The DTC-SVM scheme of the HEFS using the proposed position sensorless method exhibits good steady-state and dynamic performance, which is verified by experimental results.
