“…In [34], a harmonic compensation strategy considering different angle displacements is proposed, the dominant order current harmonics are selected by means of the generalized integrator and suppressed by model based control approach. In [35], an on‐line dead‐time compensation method for dual three phase induction machine is proposed. However, the effect of harmonic suppression depends on the stator resistance and the stator leakage inductance.…”

For the dual three-phase permanent magnet synchronous motor(dual-PMSM), the deadtime can introduce fifth and seventh current harmonics, and they are only constrained by the small stator leakage impedance, which means even if there are only small fifth and seventh voltage harmonics, the resulting fifth and seventh current harmonics will be very large. The harmonic current will make an increment of the system loss, thus lead to an reduce of the efficiency of the speed control system. This paper proposes a harmonic current suppression strategy for dual-PMSM based on least mean square (LMS) adaptive notch filter. This strategy suppresses the fifth and seventh harmonic currents by introducing four LMS adaptive notch filters in the subspace. The proposed algorithm has good dynamic performance and is insensitive to motor parameters that are offset within a certain range. The effectiveness of proposed method is verified by a set of comparative simulations and experiments.
