As China's energy demand continues to rise and the energy supply gap is increasing, engines are the main source of power for transportation vehicles, and the exhaust gas energy emitted from engines has a high recycling value, and it is important to use exhaust gas energy for power generation. This paper analyses engine exhaust data based on data fusion theory to address the problem of engine exhaust gas utilisation. This paper uses data fusion to filter and fuse multi-dimensional engine exhaust gas monitoring and sensing data, establish an engine exhaust gas power generation system, use exhaust gas turbocharging technology to utilise exhaust gas energy, and improve engine performance and exhaust gas emission characteristics through exhaust gas reforming and hydrogen recirculation.

“…The iterations in Ref. [6] have been reduced to seven by applying space vector modulation and cost function simultaneously in the FS‐MPC. However, these existing methods for computational burden reduction [6, 33, 35–37] require extra information, such as the polarity of ZSC, ZSV position, flux position, or VV position.…”

A sampling error‐based finite‐set predictive current control (FS‐PCC) is proposed in this article for the open‐end winding induction motor (OEWIM) drive. The proposed scheme controls the zero‐sequence current (ZSC) alongside the stator currents. In a model‐free approach, this method predicts the future of ZSC and stator current components by the stator current and voltage sampling errors. In this way, the parameters of the OEWIM are not utilised in the prediction algorithm of the FS‐PCC. So, the proposed method is robust against the variation of the parameter. Moreover, this article presents a simple vector selection technique for the FS‐PCC of the OEWIM. The proposed technique has two cost functions and a simple algebraic equation to put the voltage vectors (VVs) in the prediction algorithm. The first cost function uses VVs that do not have the zero‐sequence voltage component. Then, the algebraic equation determines VVs that must be utilised in the second cost function. Finally, the optimum VV is selected by the second cost function. In the proposed scheme, the prediction algorithm is iterated 14 times instead of 27 iterations of the conventional predictive algorithm. So, besides establishing a novel model‐free prediction algorithm, the proposed method has almost 50% fewer calculations. The validity of the proposed sampling error‐based FS‐PCC and the simplified vector selection technique has been verified through experimental tests.

Summary This paper presents two nine‐level inverter topologies for open‐end winding induction motor drive with fault‐tolerance for all possible switch faults. The proposed topologies are designed with three voltage‐source inverters each with eight switches, an isolated DC source and a capacitor. The number of components and the scheme of connection employed for phase windings in both the topologies are identical. The voltage across the capacitors is controlled using the phase currents and hence does not require any additional pre‐charging circuit. The direction of phase currents flowing through the capacitors determines their charging and discharging states. Hence the proposed topologies are categorized as flying‐capacitor leg based topology (FCLBT) and switched‐capacitor based topology (SCBT) considering the technique employed for generating intermittent voltages. Although these topologies require three sources, the output voltage peak across each phase winding would be twice the source voltage, hence lower rating renewable energy sources can be employed as input sources. Conventional level‐shifted carrier sinusoidal pulse width modulation technique (SPWM) is employed for generating switching pulses. The proposed topologies employ reduced number of devices compared to existing similar nine‐level topologies and also exhibit fault‐tolerance for switch faults. The post‐fault operation of the proposed topologies does not require any additional hardware but necessitates the modifications of switching pulses. Simulations are performed in the MATLAB/Simulink environment and results are presented. A prototype is constructed to validate the performance of the proposed topologies and experimental results are presented.
