“…For the suppression of torque ripple, some scholars have proposed an optimized pulse width modulation (PWM) control. Accurately predict the voltage ratio and duty cycle according to the information of motor operating parameters [11], [12]. Y. Cheng and C. Zhao combined both direct instantaneous torque control (DITC) and PWM control with segmented control.…”

In view of the large current peak and torque ripple in the actual current chopping control of switched reluctance motor, a segmented PWM duty cycle analysis method of switched reluctance motor based on current chopping control is proposed in this paper. The method realizes the control of the winding current by adjusting the average voltage of the two ends of the winding in one cycle through the PWM duty cycle. At the same time, according to the inductance linear model, the conduction phase is divided into a small inductance region and an inductance rising region, and the analytical formulas of PWM duty cycle in the two regions are deduced respectively. Finally, through matlab/simulink simulation and motor platform experiment, the current chopping control is compared with the segmented PWM duty cycle analysis method in this paper. Simulation and experimental results show that the segmented PWM duty cycle analysis method can effectively reduce the current peak and torque ripple, and has high practical application value.

“…A simplificação da modelagem matemáticaé de particular interesse quando se deseja desenvolver sistemas de controle para a máquina baseados em Controle Vetorial (Blaschke (1972)), uma vez que a estratégia de controle parte de tais equações. Vários trabalhos têm discutido simplificações para o modelo dq0 da máquina de relutância chaveada e dos métodos de controle, destacando-se as tentativas mais recentes e modernas, Nakao and Akatsu (2016), Nakao and Akatsu (2017), sem no entanto conseguirem suprimir as componentes no eixo zero e o acoplamento entre os demais eixos. Krishnan (2001) cita, dentre outros trabalhos, Ilic-Spong et al (1987) e Husain and Ehsani (1996).…”

As equações das máquinas de relutância chaveada nos eixos de referência dq0 são complexas. Esse fato faz com que o controle de torque de máquinas de relutância chaveada usando Controle Vetorial seja um processo árduo. Ao longo das décadas, modelos matemáticos usando fluxo concatenado e indutância como variáveis de estado e o método de Controle Direto de Torque foram desenvolvidos para contornar os problemas de complexidade mencionados. Neste artigo, propõe-se uma estratégia simples de controle de torque de máquinas de relutância chaveada usando Controle Vetorial. O método aqui apresentado utiliza a transformação dqx, que é uma generalização da transformação Park, e a derivada da indutância como variável principal. Os resultados de simulação mostraram que a oscilação do torque diminuiu 11 vezes e o fator de oscilação do torque diminuiu 13 vezes em comparação com o controle chaveado tradicional. Além disso, usando a estratégia proposta neste trabalho, o enfraquecimento e enriquecimento de campo se tornam simples e diretos, aumentando a flexibilidade de operação desse tipo de máquina. A formulação matemática, bem como os resultados teóricos e de simulação para uma máquina de relutância chaveada 6/4 são discutidos. Também são apresentados resultados de simulação para enfraquecimento e enriquecimento de campo.

“…The electro-hydraulic, electromagnetic and regenerative active suspension systems stabilize the vehicle motion and provides comfortable ride with safety [10]. The non-linearity disturbances and uncertainty with suspension systems can be regulated by utilizing various control methods like sliding mode control, robust H∞ control, preview control, optimal control used for the controllers [11,12].…”

To achieve the stability for in-wheel suspension system of electric vehicle, the feedback controller gains of proportional-integral, proportional-integralderivative, and cascaded proportional-integral-proportional-derivative controller are tuned using a meta-heuristic based flower pollination algorithm to obtain the vehicle handling stability and control. Simulations using proposed algorithm are compared with other methods to showcase the effectiveness of the selected algorithm. The results are indicating better stabilization of suspension systems in regard to displacement and acceleration of vehicle body and wheel. IntroductionThe demand of electrical vehicles has been accelerated in recent years primarily due to the increase in consumable fuel prices and consumption. The air quality index of the metro cities is dropping with the air pollution caused by conventional vehicles. The gasoline vehicles convert approximately 17-21% of the fuel to power the wheels whereas about 59-62% of electrical energy obtained from the grids by electric vehicles can be converted into useful mechanical energy as per the U.S. Environment Protection Agency [1]. Therefore, the usage of electrical vehicle is future because it reduces air pollution, helps to improve climate changes and global warming. However, the batteries used in these vehicles have disposal issues because of harmful chemicals used in it [2,3].The mechanical propulsion system of electric vehicles may have amalgamated motor driven and in-wheel motor driven arrangement. These in-wheel electric motors are installed to obtain measurable high torque. Apart from this, the configuration has
