By using the energy dissipation theory and the property of the switched reluctance motor, this paper presents a nonlinear controller for the planar switched reluctance motors (PSRM). Based on the fact that the electrical time constant is much smaller than the mechanical time constant, the whole PSRM driving system is treated as a two-time-scale system and can be decomposed into two subsystems (...
Switched Reluctance Motor is a rotating electric machine where both stator and rotor have salient poles. Switched Reluctance Motor (SRM) drives are gaining attention due to their extremely rugged construction and fault-tolerant capabilities, which prove that SRM drives, are highly suitable for variety of industrial applications. In this paper, FPGA based digital controllers are designed for a 6...
Recently, many vehicles have applied electric parts for saving fuel consumption and reducing levels of environmental pollution. ISG (Integrated Starter and Generator) system is one of main electric parts of following these trends and can improve fuel efficiency. If ISG motor and inverter are driven by appropriate switching time, it can be a more efficient system operation than existing ISG oper...
The Switched Reluctance Motor (SRM) processes great application potential in In-Wheel Motor (IWM) electric vehicles (EV). However the problem of vibration and noise is always a disadvantage of this kind of motor. By utilizing the analytical Fourier fitting method, a convenience method for modeling In-Wheel Switched Reluctance Motor (IW SRM) is proposed for EV applications. And the negative vibr...
This paper presents a position sensorless closed loop control of a switched reluctance linear motor. The aim of the proposed control is to damp the position of the studied motor. Indeed, the position oscillations can harm some applications requiring high position precision. Moreover, they can induce the linear switched reluctance motor to an erratic working. The proposed control solution is bas...
Steady-state dynamic simulation of a variable reluctance stepping motor is carried out by applying two different excitation voltages. First a single-step voltage is applied to the motor, and a sinusoidal voltage, as the first term of Fourier series of the single-step voltage, is then used as the input voltage of the motor. In both cases plots of machine torque, current and speed are presented. ...
مسئله لرزش و نویز در موتورهای sr (موتور مدار مغناطیسی کلید شونده یا switched reluctance motor) در مطالعات علمی و تجاری متعدد به عنوان اصلی ترین گلوگاه طراحی در این فن اوری ذکر شده است . در سالهای اخیر با استفاده از کنترل هوشمند پیشرفتهای زیادی در حل این مشکل بدست آمده است . اما بیشتر مطالعات و راه حلهای ارائه شده در مورد لرزشها و نویزهای ناشی از ریپل گشتاور بوده است . با این حال براساس مطالعات ...
drives are designed to increase product performance and system efficiency. One such motor type which can benefit from digital control is the switched reluctance (SR) motor. The SR motor brings advantages in both cost and reliability over other types of adjustable speed drives. These include its simple mechanical construction, high efficiency and high power density. On the other hand, large torq...
The combination of a 16 inch Pitot tube pump with a switched reluctance motor represents a significant development in the field of high-pressure pumping. A field proven Pitot tube pump design has been mechanically integrated with a high performance switched reluctance motor. The resulting system is approximately 40 percent of the size of the standard unit it replaces. The closecoupled pump elim...
A fuzzy-logic-based turn-off angle compensator for torque ripple reduction in a switched reluctance motor is proposed. The turn-off angle, as a complex function of motor speed and current, is automatically changed for a wide motor speed range to reduce torque ripple. Experimental results are presented that show ripple reduction when the turn-off angle compensator is used.
