“…China started the research and application promotion of SRM in the 1980s and launched the domestic KC series SRM in the 1990s. To date, SRM has been successfully applied in dozens of industries, such as electric vehicles, oil exploration, lifting, home appliances, textile machinery, and machine tools [12][13][14][15].…”

Rapier looms are currently important equipment in the weaving process. The control system of the loom determines the performance of the loom, to a large extent. To effectively reduce the production cost and energy consumption and to improve the start-up performance and production efficiency of rapier looms in industrial production, this paper develops an integrated rapier loom control system based on the direct drive of a switched reluctance motor (SRM) spindle and conducts field tests and applications. The contribution and innovation of this paper is to develop a complete set of low-cost control systems, propose an SRM single neuron fuzzy PID speed control strategy based on voltage chopping control and use it for the control of the main shaft drive technology of rapier looms. The integrated rapier loom control system based on the SRM spindle direct drive proposed in this paper reduces the production costs and energy consumption and improves the start-up performance and production efficiency of the rapier loom. This text carries on the systematic plan design to the control system from the hardware system and the software system. First, according to actual needs, starting from the aspect of reducing control costs and combined with the characteristics of embedded systems, such as tailorability, low cost, and strong scalability, this paper proposes a control system hardware structure based on CAN bus communication and a fully embedded STM32. The control system is divided into multiple control modules, such as the main control module, the spindle drive module, and the power transmission coil module. The system conducts a distributed control to the loom through the CAN bus and is equipped with various communication interfaces, such as Ethernet and RS485. Second, combining the characteristics of the SRM with a simple structure, a large starting torque and the operation mode of the loom, the basic control mode of SRM voltage chopping control is determined. To improve the efficiency and start-up performance of the speed control system, the SRM single neuron PID control algorithm is proposed, and a single neuron is used to improve the PID parameters. On this basis, fuzzy control is introduced to adjust the output gain of a single neuron PID control online to improve the system performance and reduce system energy consumption. Finally, the entire set of rapier loom control systems was verified, tested and debugged on site. The results show that each functional circuit works normally, and that the designed control system can meet the speed response demand of the loom at 850 rpm and reduce the production cost and energy consumption. The comparison experiment between the single neuron fuzzy PID algorithm of the motor and the traditional PID control algorithm in the actual loom production process proves that the proposed control algorithm has a better dynamic response performance. The proposed control algorithm effectively improves the starting performance and production efficiency of rapier looms and meets the actual needs of...

“…The overlap angle limit indicated in (13) forces the outgoing phase torque reference to fully decay to zero before the aligned position (30°). Otherwise, if the overlap angle is selected beyond this limit, then the non-zero phase torque reference at the negative slop inductance zone (>30°) will generate a negative torque according to (2).…”

Torque Sharing Function (TSF) approach can be considered a promising method to solve the torque ripple issue in switched reluctance motors (SRMs) drives at low and medium speed ranges. However, at the high-speed operation of the machine, the actual phase current fails to track the reference current profile. This limitation primarily occurs over the demagnetization period of each phase current. Consequently, each phase torque will also fail to track its corresponding reference torque created by the TSF strategy. As a result, of the torque tracking error, a considerable torque ripple will be produced. To address this issue, a novel hybrid TSF is proposed in this research article. The hybrid TSF can adapt during the real-time operation relying on the current (and thus the torque) tracking capability during the magnetization period, which is much higher than during the demagnetization period. At each electrical cycle, the rising part of the incoming phase torque reference is re-profiled to mirror the declining part of the actual torque of the outgoing phases. And therefore, the torque tracking error can be compensated, and a remarkable torque ripple suppression will be attained. Additionally, within the hybrid TSF, an overlap angle controller is also proposed in this work and participated in high-speed operation. The controller keeps monitoring the error between the commanded torque and the actual average torque of the machine, and by adjusting the overlap angle in real-time, the error can be further compensated. Thus, further torque tracking capability is attained. A set of simulation results are presented and favorably compared with other traditional TSF approaches to demonstrate the feasibility and validity of the proposed hybrid TSF.INDEX TERMS Switched reluctance motor, hybrid torque sharing function, indirect instantaneous torque control.

“…Developments for SRMs are not only on better design of the machine itself, but also on advanced control strategies [25]. Because of their valuable advantages, SRMs are being widely used in industrial, agricultural and electric vehicle applications [26][27][28][29][30]. The physical appearance of a SRM is similar to other rotating motors.…”

Renewable energy sources supplied motor applications are being studied widely by researchers. As it is especially focused on design and control of such systems, studies on performance analysis approach is limited. It is vital to determine the operating behaviour of motor loads when they are supplied by limited energy sources like photovoltaic (PV) systems. According to this necessity, in this study, a switched reluctance motor (SRM) which is supplied by a PV system is analysed in terms of speed, current and torque data. Because of its advantages as it can be controlled over a wide range, its reliability and stability, SRM was used for analysis. Such data are observed in two cases, PV system irradiance change and fault conditions. System is designed as direct-fed, which is not include any storage unit. Therefore, any changes at supply system directly affect motor parameters. These effects and results are discussed by using the graphs that obtained from various points of system for both cases.
