Sensorless control of SRM using magnetizing curves
AbstractAmong various variable speed drives, switched reluctance motors (SRMs) have been found to be competitive with traditional ac and dc motors because of their simple construction and drive electronics. However, the necessity of using a shaft‐mounted position sensor is one of the drawbacks of the SRM from the standpoint of cost, size, and ...

Mitigation of cross-saturation effects in resonance-based sensorless switched reluctance drives [PDF]
The stator and rotor yoke in a switched reluctance motor form magnetic circuit parts that are typically shared by different phases. If these parts saturate due to the excitation of one phase, this will lead to a change of the magnetic characteristics of ...

Remote power control strategy based on virtual flux approach for the grid tied power converters [PDF]
The control of active and reactive power for the Renewable Energy Sources (RES) based power plants are very important. The injection of active and reactive power to the grid is normally controlled at the Point of Common Connection (PCC) where this point ...

Self-Commissioning Algorithm for Inverter Non-Linearity Compensation in Sensorless Induction Motor Drives [PDF]
In many sensorless field-oriented control schemes for induction motor (IM) drives, flux is estimated by means of measured motor currents and control reference voltages.

An analysis of the benefits of signal injection for low-speed sensorless control of induction motors
We analyze why low-speed sensorless control of the IM is intrinsically difficult, and what is gained by signal injection. The explanation relies on the control-theoretic concept of observability applied to a general model of the saturated IM.

Improved Sensorless Control of Interior Permanent Magnet Sensorless Motors Using an Active Damping Control Strategy [PDF]
This paper proposes the active damping control strategy for position sensorless operation of an interior permanent magnet (IPM) motor. The proposed method is applied to both the current controller and the position estimator to control damping characteristics of the IPM drive system.
