Position-Sensorless Control of Switched Reluctance Motor Drives: A Review

With the ever growing environmental concerns, renewable energy sources emerge as a promise of clean and abundant energy, enabling long-term sustainable development. In this context, wind power gained significant interest due to its relative low cost and availability. Switched reluctance generators (SRGs) are suitable candidates for wind energy conversion systems, as they present a simple structure, robustness, a wide range of speed and are capable of operating in harsh environments. The machine, however, poses challenges such as high torque ripple, acoustic noise production and highly nonlinear behavior. Nonetheless, with the use of adequate control strategies, high dynamic performance SRG-based wind energy conversion systems can be achieved. As a result, this article presents a state of the art review of SRGs in wind power applications. First, the fundamentals of the SRG are presented. Next, two categories of firing angle control are reviewed: optimization and closed-loop control. Then, voltage and power control strategies are discussed, being divided in model-independent and model-based approaches. After that, a review on grid-tied SRGbased wind energy conversion systems is carried out. The most common filter topologies as well as the employed control strategies are detailed. Lastly, an outline of the discussed topics is presented and future trends as well as suggestions for future investigation are listed.

This study presents the challenges faced while implementing a new converter topology for switched reluctance motor (SRM) drives. A novel converter configuration that can excite the motor directly from the grid supply, i.e., alternating current supply, was proposed in earlier research. The proposed converter topology is designed to draw power directly from an AC grid. This converter is a modified version of the R-dump converter. There are many converter topologies available for excitation of SRM. The uniqueness of the converter topology developed in this research shows that it can use 4 switches per phase, which in turn increases the redundancy of the whole system. Moreover, this topology is well suitable for SRM excitation since the machine coil structure is constructed with 4 coils and 5 terminals. Since this novel converter is having the advantages of operating in AC input voltage, it improves the usefulness of SRM in household applications such as washing machines, hair dryers, and vacuum cleaners. An analysis of real-time implementation challenges faced while realizing the universal R-dump (URD) converter is presented with discussion to overcome the challenges. An experimental setup is made to verify the converter working.

“…Although the SRM has many good characteristics, its unique double-salient structure causes itself to have a relatively serious torque ripple during operation, especially at low speeds. The motor's strong nonlinear characteristics also make the reluctance motor's servo control more difficult [2].…”

Switched reluctance motors are widely used in household appliances, textile machines, electric vehicles, and other fields due to their simple structure, low cost, high reliability, high efficiency, large starting torque, and wide speed regulation range. With the continuous expansion of the application field of SRM, higher requirements are put forward for the design of the motor position servo control system. The control system should be highly accurate and easy to deploy and have strong anti-interference. Based on the traditional switched reluctance motor control method, this paper designs a feedforward control position loop and applies CVC control at low-speed conditions to optimize the accuracy, anti-interference, and torque ripple characteristics of position servo control. The simulation results prove that the design results of the servo control system are correct and effective.
