Multi-phase machines are increasingly used as Voltage Vector (VV). The control action is obtained miniin research and industry applications due to their inherent mizing a cost function (CF) having several objectives balanced advantages. Stator current control is a common strategy by Weighting Factors (WF). Previous works have considered face for this type of systems. The most important issue it must is regulation of currents in the torque producing plane parametric tuning of the CF [2]-[4], as well as the design and the harmonic plane. For this task, Finite Control Set of parameter-free CFs [5], [6]. However, it has been shown Model Predictive Control (FCS-MPC) constitutes an inter-that trade-offs between figures of merit are unavoidable by esting alternative to methods using modulation. However, simply adjusting the CF [7], [8]. Researchers have considered the implementation of FCS-MPC is characterized by a high reducing the sampling period to improve current tracking. This computational demand, limiting the sampling frequency.work proposes a predictive algorithm that needs less In addition, wide-band converters achieve high commutation computation time. As a result, the sampling period can frequencies, needing high sampling frequencies [9]. However, be reduced while producing predictive control. This brings FCS-MPC is intensive in computation. As a result, a limit about several benefits resulting from improved current on the sampling frequency is found for any given computing tracking. The proposed method avoids the combinatorial hardware. Fast computation of the control action has become time-consuming optimization phase of standard FCS-MPC which is the most part. The algorithm is based on physical an interesting research topic in recent years. The case of threeinsights obtained from the application of FCS-MPC to multi-phase converters is easier to study as there are no x−y currents phase drives leading to the concept of evolutionary gaps and the dynamics of the load is simpler [10].

Moreover, the method been restraining the combinatorial space. For instance, in [11] tween is flexible enough to balance the trade-off appearing bethe torque producing plane and the harmonic plane. the Voltage Vector (VV) search is restricted to an area within 60 degrees of the voltage space diagram.

“…The efficiency of the D4WD drive is better, i.e., 87.5∼89.3 % during wide range of speed variations. Again, the proposed LUT-DTC performance is compared with the different scheme presented in [11], [12], [15]- [20], [31] and the various performance parameters are shown in Table VI. It is observed that the proposed LUT-DTC is better with various performance support such as SoC, circulating current with reduced torque and current ripple.…”

Induction motor powertrains are emerging as a cost-effective option for high-power electric vehicles (EVs). A differential four-wheel drive (D4WD) EV based on two open end winding induction motor (OEWIM) propulsion is presented in this paper. Each OEWIM is driven by two 2-level voltage source inverters (VSI) with two isolated battery packs as the source. The proposed drive control algorithm integrates the uniform state-of-charge (SoC) distribution and fault-tolerant operation. A two-stage lookup table (LUT) based direct torque control (DTC) scheme is proposed to balance the SoC of batteries by selecting the suitable redundant VSI voltage vectors. The proposed LUT-DTC scheme is less sensitive to variations in motor parameters and provides excellent steady-state and transient performance. The results show the superiority of the proposed controller in terms of battery SoC balancing. The performance of the EV drive with the proposed LUT-DTC is validated by both simulation and laboratory experiments for the FTP75 and HFET driving cycles under different operating modes under normal and fault conditions. The dual motor driven D4WD with the proposed LUT-DTC is found to achieve 89.2% efficiency.

Unified coordinated control strategy for two parallel inverters TPOW-PMSM system

The three-phase open-winding permanent magnet synchronous motor (TPOW-PMSM) is generally used to drive electric vehicles. The voltage vector spatial distribution and fault-tolerant topological structure of a TPOW-PMSM system with two parallel inverters are analyzed in this paper. Then, based on the unified PWM modulation algorithm, a unified coordinated control strategy based on reference voltage vector 120º decoupling control is proposed. The speed and current double closedloop control systems of two parallel inverters are designed, and a PI + repetitive controller of the speed loop is designed to realize fast and stable speed control. The realization process does not require sector judgment or table lookup calculations, and the switching time of each bridge arm switch tube is determined by the instantaneous value of the three-phase voltage of the two parallel inverters, which simplifies the control algorithm. Experimental results show that the unified coordinated control strategy with the PI + repetitive controller can control the normal operation of a TPOW-PMSM, and realize smooth and reliable transitions from the normal operation state to the fault-tolerant operation state. The proposed unified coordinated control strategy with the PI + repetitive controller effectively suppresses the instantaneous value of system zero-sequence current, and inhibits the influence of the dead zone effect.
