FPGA Field Oriented Control of an Axial Flux motor-in-wheel [PDF]

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
This paper presents the design and the prototype implementation of a three-phase power inverter developed to drive a motor-in-wheel. The control system is implemented in a FPGA (Field Programmable Gate Array) device. The paper describes the Field Oriented Control (FOC) algorithm and the Space Vector Modulation (SVM) technique that were implemented. The

Field-Oriented Control of Multiphase Drives With Passive Fault Tolerance

IEEE Transactions on Industrial Electronics, 2020
Multiphase machines provide continuous operation of the drive with no additional hardware in the event of one or more open-phase faults. This faulttolerant capability is highly appreciated by industry for security and economic reasons. However, the steadystate post-fault operation has only been feasible in previous works after the fault localization ...
