Abstract :
A robust field weakening method for direct torque controlled PMSM drive system was proposed. The basic idea is to adjust the flux reference on the basis of voltage error, which changes with variable states of motor. Furthermore, a unified method of determining flux reference in the whole operating range is given. In the end, this robust field weakening method was validated by simulation and experiment, and the results exhibited good performance of control.
