Commutation between the two phase windings in the dc fan takes place electronically by alternately applying power to L1 and L2. Dead zones between the power pulses limit current for speed control and helps minimize a cogging effect when the rotor magnets align with the stator coils. The on-and-off power of the commutation periodFile Size: KB. Fuzzy, neural and evolutionary computing are the three major themes of soft computing. The book presents original research papers dealing with the theory of soft computing and its applicatioos in engineering design and manufacturing. The methodologies have been applied to a .
Conventional direct torque control (DTC) is one of the excellent control strategies available to control the torque of the induction machine (IM). However, the low switching frequency of the DTC causes high ripples in the flux and torque that leads to an acoustic noise which degrades the control performances, especially at low speeds. Many direct torque control techniques were appeared to Cited by: 4. The following outline is provided as an overview of and topical guide to electrical engineering.. Electrical engineering – field of engineering that generally deals with the study and application of electricity, electronics and field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical.

A general neural-network-based connectionist model, called Fuzzy Neural Network (FNN), is proposed in this book for the realization of a fuzzy logic control and decision system. The FNN is a feedforward multi-layered network which integrates the basic elements and functions of a traditional fuzzy logic controller into a connectionist structure.
Thus, traffic signal control is a suitable task for fuzzy control. Indeed, one of the oldest examples of the potential of fuzzy control is a simulation of traffic signal control at an intersection of two one-way streets. Even in this very simple case, the fuzzy control was at least Cited by: 1.
In this study a fuzzy neural network (FNN) control system with adaptive algorithm is proposed to control permanent magnet synchronous motor (PMSM) drive system. Abstract. In this paper, a two-phase evolutionary optimization scheme is proposed for obtaining optimal structure of fuzzy control rules and their associated weights, using evolutionary programming (EP) and the principle of maximum entropy (PME) based on the previous research .Author: Chi-Ho Lee, Ming Yuchi, Hyun Myung, Jong-Hwan Kim.

The mathematic Two-phase fuzzy control. book of the two-phase hybrid stepping motor and the structure of Fuzzy-PID controller are detailed, and the simulation model of Fuzzy-PID controller in MATLAB/simulink is also by: 8.
Control ot two-phase induction motor by changing the phase difference angle. Book, Purdue University, international edition Fuzzy control has been applied to various industrial.
Two-phase approach is thus a combination of the min operator model and the "arithmetical average" operator model. We shall show that the optimal solution yielded by the two-phase approach is fuzzy-efficient [2, 3]. Theorem The optimal decision plan x** yielded by two-phase method & by: Vector-control techniques have been well developed for PWM converters.
Various reference frames may be used for vector-control applications. Figure shows three sets of reference frames: a-b-c three-phase stationary reference frame, α-β two-axis stationary reference frame, and d-q two-axis rotational reference frame rotating at speed ω.
This book is the proceedings of the Third International Conference on Fuzzy Information and Engineering (ICFIE ) held in the famous mountain city Chongqing in Southwestern China, from SeptemberOnly high-quality papers are included.
The ICFIEbuilt on the success of previous. In this paper, a new method for the solution of distribution problem in a fuzzy setting is presented. It consists of two phases. In the first of them, the problem is formulated as the classical, fully fuzzy transportation problem.
A new, straightforward numerical method for solving this problem is proposed. This method is implemented using the α -cut approximation of fuzzy values and the Author: Krzysztof Kaczmarek, Ludmila Dymova, Pavel V.
Sevastjanov. The single-phase induction machine has the advantage of being powered by a single-phase voltage source. The availability of this power allows it to be widely used: electric household appliances, portable machine tools However, this type of machine has not yet taken its whole share from various works present until now, in comparison with the three-phase asynchronous machine.
[pic] A HIGH PERFORMANCE INDUCTION MOTOR DRIVE SYSTEM USING FUZZY LOGIC CONTROLLER [pic] VIGNAN’S ENGINEERING COLLEGE VADLAMUDI A HIGH PERFORMANCE INDUCTION MOTOR DRIVE SYSTEM USING FUZZY LOGIC CONTROLLER ABSTRACT Abstract- Basically, the motor drive system comprises a voltage source inverter-fed induction motor (VSIM):.
The control proposed in this paper is based on a hybrid approach; combines the performances of the controls which are based on the tools of the artificial intelligence (neural networks and fuzzy logic) applied to control the two-phase induction motor supplied by voltage source inverter.
The application of this approach to the two-phase induction machine is a contribution to the study of this. RuIe (3), called the two phase rule, is the source of the name two phase locking. Each transaction may be divided into two phases: a growing phase during which it obtains locks, and a shrinking phase during which it releases locks.
The intuition behind rule (3) is not obvious. Roughly, its function is to. "Essentials of Fuzzy Modeling and Control", by Ronald R. Yager and Dimitar P.

The multidimensional number partitioning problem is to split a given set of integer vectors into two disjoint subsets, such that the sums of the elements in the two subsets are equal or nearly equal on every coordinate.
This partitioning problem is in fact NP-hard. In this paper, we propose an optimization method for this problem. The proposed method involves recasting the original problem as Author: Feng Ma, Mingfang Ni. The FUSICO (Fuzzy Signal Control)-research project was started in at the Helsinki University of Technology.
The main goals of the project are theoretical analysis of fuzzy traffic signal control, generalized fuzzy rules using linguistic variables, validation of fuzzy control principles, calibration of membership functions, and development of a fuzzy adaptive signal by: In practical aggregate production planning (APP) decisions, the decision maker (DM) must simultaneously handle multiple conflicting goals that govern the use of the constrained resources.
