“…For VSI-fed multiphase drives without filter, several closedloop control approaches have been developed. These include sensorless rotor flux (field) oriented control (FOC) [8]; direct torque control (DTC) [7], [9] for improved steady-state and dynamic response; model predictive control (MPC) [10], [11] to obtain optimal performance within user-defined constraints during model parameter variations; and fuzzy logic-based finitetime and command-filtered adaptive backstepping control [12] to handle uncertainties such as input saturation, external load disturbances. DTC and MPC provide variable switching frequency to obtain optimal flux and torque requirements, while FOC and direct self-control strategies [7] utilize several carrierbased pulse width modulation (PWM) techniques [13].…”

Only precise industrial applications can benefit from the high-frequency performance of variable-speed drives with low switching losses. A five-phase induction motor (FPIM) is connected to a voltage source inverter (VSI) via a LC filter (low pass filter) to reduce high-frequency losses in the motor. A five-phase sinusoidal voltage is used to lower the high dv/dt at the motor terminals. However, sustained resonant frequency oscillations destabilize closed-loop control of the FPIM drive at certain operational points. This paper presents and analyzes a variety of high-frequency SVPWM techniques, both continuous and discontinuous. It is also possible to optimize the switching frequency of the five-phase two-level VSI fed FPIM drive using an improved current ripple prediction method. Auxiliary circuits and high-frequency sensors are not necessary in this system, making it more stable. Simulated and experimental results are used to evaluate the stability of a drive under a variety of conditions.

“…In the recent state-of-the-art, the finite-set MPC represents one of the commonly suggested techniques for high performance dynamic control of induction machines due to its simplicity, ease of implementation with non-linear constraints, lower switching frequency and the unnecessary modulation stage [23]. The implementation of the finite set predictive current control (PCC) and finite set predictive torque control (PTC) techniques to multiphase machine drives has been extensively addressed in several recent studies [22,[24][25][26][27]. These techniques utilize a cost function to select the optimal vector that minimizes the error between the predicted and the reference values using a preadjusted and normalized weighting factors.…”

“…In the same context, a remarkable effort has been done to overcome the MPC challenges, such as variable switching frequency, weighting factor design, and current waveform quality [25, 28] [29] . The concept of virtual vector has widely been employed as a possible and promising technique to concurrently improve the waveform quality and eliminate the weighting factors [24,26,27,30,31]. Ref.…”

Effect of Winding Design on the Performance of Predictive Current Control of Six-Phase Induction Machine-Based Propulsion Systems

et al. 2022

Electric propulsion based on six-phase machines in marine propulsion and automotive traction applications are undergoing rapid development due to its high capacity, fault tolerance, reduced size, and reduced torque pulsations. Among different control techniques of six-phase machines, direct controllers, such as finite control set model predictive control (FCS-MPC), have extensively been studied in recent literature. One of the main problems of this controller type is the relatively poor current quality due to circulating xy current components. This problem has been tackled in literature through enhanced control techniques and/or winding design. Following both approaches, this paper extends a previous study to deeply investigate the effect of winding design on the performance of the model predictive control applied to a six-phase induction machine (SPIM). Three six-phase winding layouts have been compared, namely, dual-three phase (D3P), asymmetrical (A6P) and symmetrical (S6P) configurations. The main objective of this study is to investigate the effect of winding chording when standard three-phase stator frames are employed on the current quality of different winding configurations under classical predictive current control (PCC). A 1.5Hp prototype system has been used for this experimental comparative study.

SummaryThis article narrates a robust sensor‐less indirect rotor field‐oriented control (IRFOC) of a six‐phase asymmetrical induction motor (SPAIM) drive with an online estimation of parameters and reduction of common mode voltage (CMV). In comparison to the conventional IRFOC technique, the proposed IRFOC provides the least CMV using modified space vector modulation (SVM). To guarantee proper operation of IRFOC, accurate estimation of rotor time constant is mandatory; any mismatch in the actual and tuned value may lead to poor performance of the IRFOC algorithm. This problem will be further accelerated with encoder‐less control using model‐based estimators. In this manuscript, the problem of simultaneous estimation of speed and machine parameters is investigated, and a model reference adaptive system (MRAS) based speed estimator accompanied by online estimation of parameters is proposed to improve sturdiness against variation of parameters. A Simulink model of the proposed method is developed and a simulation study is carried out. To validate the simulation results, a scaled prototype model of The SPAIM rated for 2 HP, 200 V is developed and encoder‐less IRFOC for the SPAIM drives is implemented using an STM32F407VG controller board. The performance of the proposed observers is tested and verified for all the possible operating conditions and results are presented.
