“…In the second group, the solutions [18][19][20][21][22] tend to improve the efficiency aspect of the ITC which is applied for the constant torque region to mainly minimize the torque ripple and produce smooth torque.

The priority of smooth torque often leads to a trade-off with the efficiency and the proposed methods tend to reduce such compromise.…”

In this paper, the intermittent control is proposed for switched reluctance machine drive to both increase the efficiency and decrease the cost of the traction system for low-cost electric vehicles. With the purpose of maintaining the average machine torque required by the load, the intermittent control imposes a higher phase torque during a shorter time. The simulation and experimental results achieved with three different switched reluctance machines show that the intermittent control increases the system efficiency by reducing the converter losses and the core losses. Additionally, three different strategies of the control have been proposed to analyze their impact automotive application based on the criteria of efficiency, machine vibration and torque pulsation. It can also be easily applied for any switched reluctance machines using average-torque-controlbased methods.

Este artigo apresenta um controlador Linear com Parâmetros Variáveis (LPV) robusto na estrutura RST (Reference Signal Tracking) para o controle de velocidade de uma Máquina de Relutância Variável (MRV) 6/4. Esta máquina possui um simulador que considera as não linearidades presentes na operação da MRV. A dinâmica da malha de velocidade foi baseada em um modelo ARX LPV identificado para uma determinada faixa de operação a partir de dados coletados em simulação, sendo o nível de corrente normalizado e filtrado o parâmetro variante. Em posse dos parâmetros do modelo, os parâmetros do controlador LPV foram determinados por meio de um problema de otimização convexa, na forma de uma LMI parametrizada (PLMI). Desse modo, foi observado o desempenho do controlador LPV submetido à variação dos parâmetros e comparado com controladores convencionais com parâmetros fixos.

In this paper, a novel control method based on model predictive control (MPC) and torque sharing function (TSF) is addressed to minimize the torque ripple of switched reluctance motor (SRM). Firstly, an accurate SRM model is established based on flux‐linkage characteristic curves obtained from the locked rotor test, which can predict the future operation state of the SRM drive system. Secondly, an improved TSF curve is proposed, and genetic algorithm is used to optimize TSF parameters to reduce torque ripple in commutation region. Besides, the MPC is integrated into the TSF control framework to replace the traditional hysteresis controller, and establishes a new TSF‐based model predicted torque control (MPTC) method, which avoids the frequency conversion problem caused by torque or current hysteresis controller. Further, a sector division scheme is addressed to decrease the number of candidate voltage states, whereby the computation of the controller in each sampling period is effectively reduced. Finally, in order to verify the correctness of the MPTC method, it is compared with the traditional direct instantaneous torque control (DITC). Both simulations and experiments on a three‐phase 12/8 pole SRM have confirmed that MPTC scheme can not only decreases torque ripple and stator copper losses, but also has higher efficiency than DITC. © 2021 Institute of Electrical Engineers of Japan.
