Sensorless Field Oriented Control of PMSM Drive System for Automotive Application

Reconfigurable Control of PWM AC-DC-DC Converter without Redundancy Leg Supplying an AC Motor Drive

“…Since there is 6 voltage references and only 5 legs, a reduction in the number of voltage references is required. Reduction of the number of voltage references can be made by using an inverse lookup table [2,11], this is realized by adding another ZSS in accordance to the converter configuration in five-leg mode.…”

“…Several researchers in the fault tolerant converter applications have obtained promising results by using an additional leg to guarantee the continuity of service, in [2], the authors studied the fault tolerant six-leg converter for a Wind Energy Conversion System (WECS) with a Doubly-Fed Induction Generator (DFIG). In [11][12][13][14], the authors treated the fault detection, isolation and compensation as an open-circuit and short-circuit tolerant motor drive system and discusses about fault tolerant AC-DC-AC single-phase to three-phase converter.…”

A Novel High Performance Discrete Flux Integrator for Control Algorithms of Fast Rotating AC Machines

“…For example, the sliding mode algorithm [2,3] requires a double integration for currents and fluxes; the Butterworth method presented in [4] present the same double integration plus the need for an additional PI regulator; the dead-beat direct control in [5] is not really ideal for flux estimation, since it looks only at the end torque result; the adaptive model of [6] or, more recently, [7,8] could be very calculation heavy; the methods compared in [9] are just for machines with magnets. Moreover, a flux observer is required for any sensorless application such as permanent magnets [10], reluctance [11], or induction machines [12] that all use the machine equations to find the rotor flux angle, since this operation is intended for applications without the direct measurement of the rotor position and speed.…”
