This paper presents a new method of detecting rotor position in Toroidal Switched Reluctance Motor(TSRM). In this paper, low cost and robust characteristics of rotor position detection method are focused in order to compensate for disadvantage of general sensors. Search coils wound through the hole of the stator poles are used for detection of the rotor position in TSRM. Rotor position detection is achieved through electromotive force patterns induced by time-varying flux linkage in the search coils and then adequate phase is excited for drive. The initial rotor position estimation method is also described. The validity of the method is verified by experimental results.

This paper suggests the torque control method that is possible to control Switched Reluctance Motor(SRM) directly without the various data: The proposed control method uses the real-time estimated torque that is based on the Linearized mechanical Work Operation(LMWO). The suggested torque control strategy is verified by simulation and experiments in this paper.

It is well known that an encoder or a resolver is necessary to obtain the position data for speed or position control Generally utilized speed sensors are mal-affected by the EMI, dusty, and high temperature surroundings. Therefore, the speed and position sensorless controls using observers have been studied widely. In this paper, the binary observer which is composed of two feedback regulation loops to control the speed of SRM(Switched Reluctance Motor) is applied. One loop compensates the control input directly like the sliding mode control, and the other one compensates the system parameters indirectly. This observer is constructed on the foundation of variable structure control on the foundation of variable structure control theory and has the inertial term for the varying parameter. The validities of this proposed method is proved by experiments.

In this paper, an optimal method for determining design parameters of a Switched Reluctance Motor is researched. The dominant design parameters are stator and rotor pole arc and switching on and off angle. The parameters affecting performance are examined and selected using evolutionary computations and commercial CAD program. The simulated design method is compared with conventional procedure.

In this paper, A fixed turn-on, variable turn-off control method considering the reference speed and load is shown with verification by using MATLAB Simulink. The proposed method uses simple operation and is suitable to the system of low-cost application and also advantageous for reducing the torque ripple.

This paper deals with the rotor vibration analysis of Switched Reluctance Motor(SRM) with the 6/4 poles. For this analysis, 3-dimensional mode shapes corresponding to the natural frequency and critical speed map according to rotor speed are presented by using 3D Transfer Matrix Method(TMM). The gyroscopic effect and shear deformation of rotor are considered.

This paper analyzed the static torque of SRM according to the variation of airgap length using Finite Element Method. The normal and tangential components of flux density are analyzed at uniform airgap field which sap length is 0.3[mm] and nonuniform airgap which gap lengths are 0.2-0.4[mm] and 0.4-0.2[mm]. Also their static torques were simulated by using Virtual Work Principle. We expect that their parameters will help for the design of Switched Reluctance Motor.

The paper deals with the fuzzy PI control of a switched reluctance motor drive. Fuzzy algorithm based on linguistic rules describing the operator's control strategy is applied to speed control of the SRM. Simulation and experimental results show that performance of the furry PI controller is superior to that of conventional PI controller. In particular the robustness of the system is improved.

SRm의 성능에 미치는 영향은 전동기 권선을 여자하는 모드에 어는 정도 의존하며, 여자모드에 전류펄스식(전류원) 또는 접압펄스식(접압원)이 있다. SRM의 운전 특성상에서 볼 때 전류원에 의한 방법이 이상적인 전원이지만, 대용량의 사용을 위한 구성이 후자에 비하여 실혐하기가 쉽지 않고 경제적이지 못하다. 본 논문에서는 지금까지 보통 상용되고 ldT는 전압원의 대안으로 가변전압원이 고려되었다. 3가지 여자 모드에 관한 비교가 제시되고, 순시 전압과 전류 파형이 실험결과로 포함된다.
