Multiple Synchronous Reference Frame Current Harmonic Regulation of Dual Three Phase PMSM With Enhanced Dynamic Performance and System Stability

Decoupled and compensated space vector pulse width modulation algorithm for dual‐channel PMSM with unbalanced power supplies

“…The proposed decoupling matrix has been applied on a dual-channel PMSM, and next is to eliminate the coupled components of inductance matrix in multi-channel PMSM. The decoupled multi-d-q modeling is successfully employed for six-phase and nine-phase machines in Gobburi et al and Yan et al 7,10 However, it is unavoidable to introduce complex calculation when constructing the proposed matrixes on multi-phase machines. To expand the channel decoupling matrix and make it simple to construct without redundant work is important for its promotion.…”

Analysis and Fault-Tolerant Control for Dual-Three-Phase PMSM Based on Virtual Healthy Model

“…So 2 nd -order harmonic currents are induced based on (24). The quasi-PR controller [40] or multiple reference frame (MRF) controller [41] can be utilized to suppress these 2 nd order harmonics while the latter one will induce more calculation burden so in this article, the quasi-PR controller is used to suppress the induced harmonics components. Compared to the traditional PR controller, the quasi-PR controller has a limited gain at the resonant frequency with a wider and controllable bandwidth, thus more robust.…”

“…According to the bode diagram and the transfer function, the Nyquist diagram is used to analysis the stability of the controller [41]. The effects of the resonant parameters, k r , ω c and the working frequency, ω r on the stability are needed to be discussed.…”

“…Moreover, other alternatives, such as the disturbance observer (DOB) [76], the extended state observer (ESO) [77] and the virtual impedance [78] are also extended to DTP PMSMs to obtain benefits in terms of performance and robustness. In particular, a multiple synchronous reference frame (MSRF) current harmonic regulation technique, proposed in [80,81] is able to decouple not only the 5th and 7th harmonics, but also the 11th and 13th harmonics in DTP PMSMs. This concept of the MSRF technique also features the potential to be extended to other multi three-phase machine systems.…”
