A resolver converter based upon a novel open-Loop Technique
(
IEEE
, 2008 , Conference Paper)
The paper presents a novel technique for the determination of the angle from slowly-varying quadrature co-sinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ...
A Discontinuous PWM Method for Balancing the Neutral Point Voltage in Three-Level Inverter-Fed Variable Frequency Drives
(
IEEE
, 2008 , Article)
The paper describes a new discontinuous carrier-based pulsewidth modulation (PWM) method for use in variable frequency drives (VFD) driven by three-level inverters. The method introduces three different switching patterns ...
A hybrid active and reactive power control with Quasi Z-source inverter in single-phase grid-connected PV systems
(
IEEE Computer Society
, 2016 , Conference Paper)
This paper presents a hybrid method of active power and reactive power control strategy with Quasi Z-source inverter (QZSI) in single phase grid connected photovoltaic (PV) systems. The maximum power from the PV panel is ...
Repetitive Control Based Pwm Inverter Dead-Time Compensation For Ac Servo Drive
(
Qatar University
, 2002 , Article)
AC servomotor speed or current controller based on PI control and/or optimal control, can not eliminate the cyclical fluctuations of speed or current when subject to periodic disturbances. However, repetitive control ...
A New Low Cost Linear Resolver Converter
(
IEEE
, 2008 , Article)
A new low cost converter topology is proposed for sinusoidal position encoders. The converter enables determination of the angle from the sine and cosine signals of the encoder. When used with resolvers, the implementation ...
A Resolver Angle Estimator Based on Its Excitation Signal
(
IEEE
, 2009 , Article)
A resolver generates a pair of signals proportional to the sine and cosine of the angular position of its shaft. A new low-cost method for converting the amplitudes of these sine/cosine transducer signals into a measure ...
An open-loop technique for angle determination from position encoders
(
IEEE
, 2008 , Conference Paper)
The paper presents a novel technique for the determination of the angle from low-frequency quadrature cosinusoidal signals produced, for example, by position sensors. In the presented scheme applied to a resolver, the ...
Iterative learning control for variable frequency drives
(
IEEE
, 2008 , Conference Paper)
Variable Frequency Drives (VFD) are subject to various types of disturbances especially cyclical ones. These periodic disturbances are difficult to compensate by conventional controllers. Repetitive control can only ...
Stability analysis of an active-damped LLCL filter- based grid-connected three-phase inverter
(
IEEE
, 2014 , Conference Paper)
Power passive filters are a standard solution for gridcurrent harmonics attenuation. However, these types of filters may cause a resonance between the inverter and the grid. Passive and active damping techniques are employed ...
Machine-Learning Based Relay Selection in AF Cooperative Networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
With the significant increase of wireless network nodes and traffic load in recent years, especially in the emerging internet-of-things (IoT) and vehicular networks, the design of a fast adaptive relay selection algorithm ...
