Computer-optimised smooth-torque current waveforms for switched-reluctance motors
The paper discusses the design of current waveforms for switched-reluctance motors, which give rise to a constant (ripple-free) torque. The waveforms are optimised by computer search techniques, to give the lowest RMS current per phase consistent with producing smooth torque. Furthermore. the waveforms are constrained to be within the converter’s VA rating. Current waveforms and the associated ...
متن کاملTorque ripple, vibrations, and acoustic noise in switched reluctance motors
The paper presents a state of the art review on the subject of torque ripple, vibrations, and acoustic noise in Switched Reluctance Motors (SRM). The approach of the multi-phase operation of SRM is also reviewed. Moreover, further directions of research on these subjects are introduced.
متن کاملAdaptive torque-ripple minimization in switched reluctance motors
This paper addresses torque-ripple reduction in current-fed switched reluctance motors (SRMs). Ripple-free torque production in SRMs requires an accurate model that is often too complex for practical implementation. The algorithm proposed here combines the use of a simplified model with adaptation. Explicitly, it includes dynamic estimation of low harmonics of the combined unknown load torque a...
متن کاملTorque ripple reduction in switched reluctance motors – A review
The generated torque ripple in switched reluctance motors (SRM) can be considered as one of the major disadvantages of the motor. It is mainly due to frequent switching of phases for rotation of the motor and changes of the air gap length between the rotor and stator teeth. It decreases the average developed torque, diminish the efficiency, causes noise and vibration in the motor. So, in order ...
متن کاملAdaptive intelligent speed control of switched reluctance motors with torque ripple reduction
Switched Reluctance (SR) motors have a wide range of applications in industries, mainly due to the special properties of this motor. But, because of its dynamical nonlinearities, its control is complex. This paper presents an adaptive intelligent control based on the Lyapunov stability theory to control the speed of SR motors with good accuracies and performances. The proposed controller compos...
