This article presents a modeling and control of the Doubly Fed Induction Motor (DFIM), associated with two inverters controlled through Pulse Width Modulation technique (PWM), DFIM is carried out by approach Rotor Flux Oriented Control (RFOC) according to direct axis. In this approach, regulation done classic PI regulators, latter having undesirable overruns static errors in non-linear systems,...

In this paper, a flexible, high computation speed and cost effective field programmable gate array (FPGA)-based speed controller for an induction motor with field-oriented control, (FOC) is presented. All the control functions including the space vector modulation based PWM waveform generation, field-oriented control algorithm and rotor flux position estimation have been realized using FPGA to ...

Two different nonlinear dynamic control algorithms are presented for synchronous motors with damping windings: (i) an adaptive speed-sensorless controller for rotor position tracking in the presence of unknown constant load torque, on the basis of rotor angle, stator and field windings currents measurements; (ii) an adaptive control law for rotor speed tracking in the presence of uncertain cons...

This paper focus on the advancement of SVPWM (space vector pulse width modulation) inverter fed permanent magnet synchronous motor (PMSM).The paper deals with a space vector pulse width modulation (SVPWM) algorithm applied to electrical drives. Anextensive and detailed study of the space vector pulse width modulation design process hasbeen done, that indicate some practical sign for implementat...

Indirect reciprocity involves cooperative acts towards strangers, either in response to their kindness to third parties (downstream) or after receiving kindness from others oneself (upstream). It is considered to be important for the evolution of cooperative behavior amongst humans. Though it has been widely studied theoretically, the empirical evidence of indirect reciprocity has thus far been...

Background and aims College students experiencing stress show tendencies to procrastinate and can develop Internet addiction problems. This study investigated the structural relationship between time perspective and self-control on procrastination and Internet addiction. Methods College students (N = 377) residing in South Korea completed the following questionnaires: the Pathological Internet ...

In this paper, a smart drive system of the induction motor (IM) is proposed and adapted for applications in electric vehicles (EVs). Objectively, EV systems are robust over wide speed torque ranges. The independent encoder (encoderless) concerned with control (TCD) indirect rotor field-oriented (IRFOC) using sliding mode observer (SMO). This arrangement monitoring techniques smartly integrated ...

This paper provides a foundation for evaluating recent changes in regulatory design in light of the increasingly competitive and dynamic environment of banking. Intrusive, control-oriented direct and indirect approaches to regulation have become very costly. Regulation that focuses on setting minimum requirements will become dominant. Supervision would then primarily aim at verifying compliance...

In this paper, a model-based predictive rotor field-oriented angle compensation approach is proposed for induction machine drives. Indirect control widely used in drives its simple implementation and low cost. However, the accuracy of affected by variable parameters such as resistance inductance. An inaccurate leads to degradation torque dynamic performance, especially high-speed flux-weakening...
