“…In order to reduce the complexity of the system, the highorder, nonlinear, multivariable five-phase IPMSM control system in the natural coordinate frame is decomposed into three mutually orthogonal spaces by coordinate transformation: fundamental space, third harmonic space and zero-sequence space [36], [37]. Since the stator winding is star-connected, the neutral point current is zero in the zero-sequence space which can be neglected.…”

Compared with the conventional three-phase motor, the five-phase interior permanent magnet synchronous motor (IPMSM) has better advantages on fault-tolerance due to redundant freedom. In order to obtain further fault-tolerance, this paper proposes a new high frequency (HF) signal-injection-based sensorless control strategy for five-phase IPMSM drives. The key is to extend the position sensorless technology based on HF signal injection into the five-phase motor control system, especially proposing a sensorless control method by injecting a HF square-wave voltage signal into the third harmonic space. The induced HF current responses in the third harmonic space can be utilized to track the rotor speed and position accurately. Compared with the conventional HF sinusoidal signal injection methods, the proposed method can effectively reduce the influence of digital filters, such as time delay and decreased performance because the low-pass-filter (LPF) is removed. In addition, the torque ripple caused by the proposed injection method in third harmonic space is reduced compared with the method in fundamental space. The effectiveness of the proposed method is verified by simulation and experimental results.

“…Both traditional and improved MPCC strategies are mostly used for the three-phase motors, while for multiphase motors, only the traditional MPCC method has been widely used with the consideration of the control complexity [17][18][19][20][21][22][23][24][25]. In [17,18], the MPCC algorithm was applied to the fault-tolerant control of a five-phase motor, and the applications for six-phase motors also have been investigated in [19][20][21][22][23][24][25]. In [25], a MPCC method involving the current harmonics suppression has been proposed.…”

Traditional model predictive current control (MPCC) for motors can only choose one optimal voltage vector during one control period, which creates problems of over-regulation or under-regulation for the current tracking. With zero vectors being injected in the chosen optimal voltage vector, the traditional MPCC can obtain better performance, which is called duty cycle MPCC. However, whether the traditional or the duty cycle MPCC is being applied to multiphase motors, it is more difficult for the phase to increase. In this paper, a general double vector-based MPCC mechanism has been studied for a dual three-phase permanent synchronous motor (PMSM) with dual Y shift 30° windings used in aerospace propulsion. Firstly, the choosing range of the second voltage vector in duty cycle MPCC was extended to an arbitrary vector; then, the cost function was rationally designed, and the delay compensation was added to improve the control performance as well. Compared with the traditional or duty cycle MPCC, this general double vector-based MPCC has better torque performance and fewer total harmonic distortions in the full speed range and under different load conditions.

Background: 3ϕ Induction Machine (IM) drives are broadly used in different industrial applications. During failure conditions, 3ϕ IM drive systems cannot continue its optimal performance. Aims: The present study presents a method for indirect rotor field-orientated control (IRFOC) of star-connected 3ϕ IM drives during open-phase failure (OPF) condition. In addition, in this study the particle swarm optimization algorithm was used to determine the coefficients of proportional-integral (PI) controllers in the OPF mode. Materials & Methods: In the proposed method, two unbalanced currents and voltage rotational matrices are utilized to change the asymmetrical structure of the faulty 3ϕ IM equations to the equations with a symmetrical structure. Using these matrices, the speed control of the faulty 3ϕ IM can be realized with minor changes in the conventional IRFOC structure including control parameters, transformation matrices, and coefficients of PI controllers. Results: Experimental results were presented during various operating conditions on a 1 HP star-connected 3ϕ IM drive system. Discussion: The experimental tests in different operating conditions showed good performances of the proposed control system during both the steady-state and the transient periods. Conclusion: The proposed control method exhibited a significant improvement in reducing the speed, torque, and flux oscillations, compared to the
