“Active Flux” Orientation Vector Sensorless Control of IPMSM
This paper presents a novel strategy for the vector control of IPMSM, without signal injection. The overall performance of the motion-sensorless control depends strongly on the accuracy of the rotor position and speed estimation. The proposed state observer is based on the concept of the “active flux” (or “torque producing flux”), which “turns all the salient–pole rotor ac machines into nonsali...
متن کاملA Sensorless Initial Rotor Position Estimation Scheme for a Vector Controlled IPMSM Drive
Vector field oriented control (VFOC) of permanent magnet synchronous motor (PMSM) drive requires accurate velocity information sensed by a speed or position sensor attached to the rotor. Nowadays, sensorless control is adopted in many industrial applications for reasons of robustness, cost, cabling and reliability. This paper presents a novel sensorless control strategy and initial rotor positi...
متن کاملA Sensorless Speed Control Using Stator Ripple Currents for an Induction Motor Drive with Space Phasor Pwm
In the present paper a simple sensorless spccd estimation scheme is presented , where the speed information is obtained from the motor phase current ripple. The scheme measures the stator current phasor deviation direction to determine the back emf vector position during inverter zero vector switching states. This measurcment of rotor flux position is done indirectly by computing the motor back...

متن کاملSeries Resonance Based Fault Current Limiter with Controlling The Point of Common Coupling Voltage
This paper proposes a novel Fault Current Limiter (FCL) for the application on distribution networks to control voltage sags at the Point of Common Coupling (PCC) during faults. This new FCL is based on series resonance including resonance transformer and series capacitor. So, by proper design of the series resonance LC tank, the fault current is limited to an acceptable level. The FCL operatio...
