Abstract: This paper presents a feedback linearization (FL) based direct torque control (DTC) for an asymmetrical six-phase permanent magnet synchronous motor (PMSM). The decoupled linear model of PMSM is yielded using the feedback linearization approach. In this way, the advantages of classical hysteresis comparator based DTC, such as fast dynamic response is preserved. The output of the feedback linearization, namely the desired vector is synthesized by four active vectors for the sake of harmonics mitigation in the secondary subspace. The existing work usually adopts the synthetic vectors with zero voltage in the secondary subspace to suppress the harmonic currents. While this practice ignores the back electromotive force (EMF) harmonics. Thus, the four-vector based space vector pulse width modulation (SVPWM) with and without considering the back EMF harmonics is investigated, respectively. The effectiveness of the proposed method is validated through experimental results. Compared with the classical switching table based DTC, the proposed FL-DTC method achieves less torque & flux ripple in the primary subspace and less harmonic currents in the secondary subspace.
