In recent time, the use of fractional-slot concentrated winding (FSCW) stator has made it possible to drive the Interior Permanent Magnet Synchronous Motors (IPMSM) in very deep flux weakening speed range. Many of such motors can operate along the maximum torque per voltage (MTPV) trajectory during the deep flux-weakening operation. Performances of...
Direct torque and flux control (DTFC) is known for its reduced torque and flux ripples compared to the classical direct torque control scheme. It can drive an interior permanent magnet synchronous motor (IPMSM) in usual control regimes while satisfying current and voltage limits of the system. However, deep flux-weakening control of an IPMSM under...
The power control of a novel fractional slot concentrated wound interior permanent magnet synchronous generator, directly driven by non-pitchable wind turbine emulator above base wind speeds is presented in this paper. The small scale fractional slot concentrated wound interior permanent magnet synchronous generator utilized has good flux weakening...
Traditionally, current vector controlled interior permanent magnet synchronous motors use two independent current regulators for flux-weakening operation. A novel flux-weakening control scheme which uses a single current regulator has been proposed recently. This paper compares the flux-weakening performance of an interior permanent magnet synchron...
The direct torque and flux control (DTFC) scheme is well known for its simplicity and less parameter dependency compared to the conventional current vector control scheme. It can drive an interior permanent magnet synchronous motor (IPMSM) in usual control regimes while satisfying current and voltage limits of the motor and inverter. If the charact...
This paper introduces a novel method to improve the reliability of a reconfigurable FPGA based elevator controller, which can be used for an elevator with any number of floors, with specified inputs and outputs. It was clear that by simply changing a variable in the HDL code the controller can be generated for an elevator with required number of fl...
