This paper presents a novel position and velocity estimation technique in four-phase switched reluctance drives based on high frequency signal injection methods. To estimate rotor position and velocity, an identical high frequency carrier voltage signal is superimposed on the main phase voltages and injected into the machine. As a result, the phase currents are composed of both main excitation currents...
This paper addresses the sensorless speed and position control of induction motors using high-frequency injection at zero and low frequencies. A novel algorithm is presented which allows the rejection of saturation and nonlinear inverter effects without the need for an offline precommissioning process. The method is based on a set of synchronous filters to identify the disturbance waveforms and a...
