The Hybrid Flux Observation Model (HFOM) is frequently employed in induction motor flux observers to ensure accurate and dynamic responses over the entire speed range. Nevertheless, voltage model, designed stationary reference frame, susceptible integral saturation drift issues. These problems lead diminished estimation accuracy compromised performance when conventional HFOM utilized. To mitiga...

In this paper, a complementary and simplified scheme to diagnose electrical faults in three-phase induction motor using the parity equations approach during steady state operation bases on stator current reference frame is presented. The proposed allows us identify phase affected due related side, such as sensors, voltage resistance. results obtained work complement detection system that uses D...

Generation systems, using renewable sources, are becoming increasingly popular due to the need for increased use of electricity. Currently, renewables sources have a role to cooperate with conventional generation, due to the system limitation in delivering the required power, the need for reduction of unwanted effects from sources that use fossil fuels (pollution) and the difficulty of building...

The general use of bilateral rather than separate renal function evaluation has led to the publication of conflicting results concerning the effect of percutaneous transluminal renal angioplasty (PTRA) on renal function, especially in patients with atherosclerotic renal artery stenosis. The aim of this study was to evaluate prospectively, in standardized conditions, split renal function (SRF) a...

In this paper, a sliding mode control is presented for direct torque and stator flux of interior permanent magnet synchronous motor in rotor speed sensorless drive system. The scheme developed specific rotating reference frame (X-Y) which the current space vector coincides with (X) axis. For technique no need to have any knowledge machine parameters such as two-axis inductances, magnets linkage...

This paper discusses nonlinear proportional-integral (PI) current control with anti-windup of reluctance synchronous machines (RSMs) for which the flux linkage maps are known. The nonlinear controller design is based on the tuning rule “Magnitude Optimum criterion” [1]. Due to the nonlinear flux linkage, the current dynamics of RSMs are highly nonlinear and, so, the parameters of the PI control...
