摘要
Abstract
In stator flux observer of direct torque control system, a low-pass filter was normally used instead of pure integrator to diminish the errors caused by DC offset and initial value. But the low-pass filter estimator would degrade estimating precision of stator flux linkage and performance of the static and dynamic state of direct torque control since it introduced magnitude and phase errors. The limitation of pure integrator and low-pass filter was profoundly analyzed. An improved stator flux estimators based on low-pass filter were introduced, the principle block diagram and simulation results comparison was presented.关键词
