Adaptive 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, 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 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 کاملOn torque ripple reduction in current-fed switched reluctance motors
This paper addresses a basic control issue in switched reluctance motor (SRM) drives—the production of a ripple-free torque. Simple and largely model-independent conventional supply waveforms are not able to satisfy this requirement. The goal of this paper is to improve SRM dynamical performance by compensating for motor nonlinearities, while maintaining the robustness of conventional methods. ...
متن کاملTorque-ripple Minimization in Switched Reluctance Motors – a Set Theoretic Approach
We present a solution to torque ripple minimization in switched reluctance motors (SRM) based on set invariance theory. We start from a piecewise affine approximation (PWA) of the overall torque characteristics over rotor angle – phase currents space and derive a PWA motor model. Within it we also take into account finite bandwidth of the phase current control loops. Using the PWA model and inv...
