Background & aim: Happiness is a mental or emotional state of well-being. Happy individuals tend to interpret and process feeling in a positive way. Accordingly, the response to the pain may alter due to the effects of subjective elements on the pain perception. This study aimed to evaluate the relationship between the level of contentment and fear of childbirth (FOC) in nulliparous women refer...

Received Oct 27, 2011 Revised Jan 2, 2012 Accepted Mar 24, 2012 This paper presents a comparative study of field-oriented control(FOC), conventional direct torque control(DTC) and proposed space vector modulated direct torque control with low pass filter(SVM-DTC). The main characteristics of FOC, DTC and proposed SVM-DTC schemes are studied by simulation, emphasizing their advantages and disadv...

Field orientation control (FOC) of induction machines has permitted fast transient response b y decoupled torque and f lux control. However, f ie ld oraentation detuning caused by parameter variations is a major dificulty for indirect FOC methods. Traditional P ID controlkrs have trouble meeting a wade ranye of tracking performance even when proper field orientation i s achieved. P I D performa...

This paper presents a comparative study on two most popular control strategies for Permanent Magnet Synchronous Motor (PMSM) drives: field-oriented control (FOC) and direct torque control (DTC). The comparison is based on various criteria including basic control characteristics, dynamic performance, and implementation complexity. The study is done by simulation using the Simulink Power System B...

The genetic organization of the foc gene cluster has been studied; six genes involved in the biogenesis of F1C fimbriae were identified. focA encodes the major fimbrial subunit, focC encodes a product that is indispensable for fimbria formation, focG and focH encode minor fimbrial subunits, and focI encodes a protein which shows similarities to the subunit protein FocA. Apart from the FocA majo...

Fractional order control (FOC) has received widespread attention in recent years due to its efficient tuning capacity, intuitive concept, and enough flexibility. Again, FOC are known be robust with the open loop gain particular. However, design of demands knowledge model modified. But on other hand, linear active disturbance (LADRC) technique is free controller. In achieve better tracking perfo...

This paper focuses on Firm-Hosted Online Communities (FOC) communities that are hosted by organizations for commercial purposes. The purpose of this paper is twofold. Firstly, we will examine examples of existing FOCs in order to develop a broader view of how FOCs have been utilized in product business. This work results with a dimensional view illustrating some discovered opportunities with FO...

One of the most important development in control area for induction motor has been field oriented control (FOC) established firstly by (Blaschke, 1972). However, the performance of this technique is affected by the motor parameter variations and unknown external disturbances. To improve the dynamic response and reduce the complexity of FOC methods, an extension amount of work has been done to f...

Abstract Field‐oriented control (FOC) has been broadly used as an accurate method for electric drives. The traditional FOC approach effectively developed to 3‐phase induction motor (3φ IM) drive systems in recent decades. Despite the usefulness of methods during normal condition, these strategies are unable a wye‐connected 3φ IM y ) under stator winding open circuit fault (SWOCF). This paper di...
