Position Sensorless Torque Estimation of Synchronous Reluctance Motors Based on Extended-Flux Model without Core-Loss Measurement
This paper proposes an extended-flux model with core-loss resistance of SynRMs (synchronous reluctance motors) and precise torque estimation without core-loss measurement and position encoder. The proposed torque estimation is useful for precise MTPA (maximum torque per ampere) control of position sensorless controlled SynRMs, which is achieved with the assistance of active and reactive powers.
متن کاملInductance Based Sensorless Control of Switched Reluctance Motor
This paper presents a sensorless control of switched reluctance motor (SRM) driven by the four phase asymmetric bridge inverter. In this method to obtain the rotor position of switched reluctance motor by means of resonant circuit method. The resonant circuit comprising of the motor and the power electronic converter, motor phase inductance and the parasitic capacitance of converter switches. F...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولVelocity-sensorless tracking control and identification of switched-reluctance motors
We present a solution to the speed sensorless control problem for switched-reluctance motors under parametric uncertainty. Our main results guarantee velocity tracking control for velocity references with constant reference acceleration under the assumption that the load torque, the rotor inertia, the resistance and inductances are unknown. Under a persistency of excitation condition on a funct...
