A three-phase pulse width modulated AC/AC voltage converter using power MOSFETs that operate in a high-frequency chopping mode is proposed. The symmetrical multipulse modulation strategy (SMM), wherein several equidistant pulses per half cycle (M), are used, is adopted. The resulting harmonic output voltages are analyzed and compared with those of phase control. The analysis reveals that substantial decrease in lower order harmonics and their selective elimination takes place with increase in M. The magnitude of the harmonic voltages is computed in terms of M and duty cycle. From the power quality perspective, it is theoretically established and experimentally confirmed that, with resistive load, for the same per unit output voltage, the supply power factor in the SMM and phase control techniques is the same

On the rigid model of a rotating machine on active magnetic bearings (AMB), the gyroscopic effects appear as two derivative cross-coupling filters between the two planes of symmetry of the shaft, with a gain depending on the inertia and linearly varying with the rotational speed. Knowing that, we can add to the controller the opposite effect, under the form of two high-pass cross-coupling filters. After the presentation of the benchmark developed by the Societe de Mecanique Magnetique (S2M, Vernon, France), a complete model of AMB machine, combining a model for a rigid suspended rotor, to a modal model of the shaft, (reduced model built from the high-order nodal model extracted from an FEM software), is exposed. Our modeling approach presents several advantages: the model is simple to obtain, accurate and of a very reasonable order, so that it is easy to simulate. We use the model obtained in order to develop a control strategy for the gyroscopic effects. The method, based on the state-space model of the system, is a generalization of a another approach, also exposed, based on a transfer function model of the AMB machine. The advantage of the method is that the tuning of decentralized controllers is highly facilitated by the fact that the system, as seen by these controllers, is independent from the rotational speed

Real time embedded system design needs a contribution between architectures model, platforms and application specification in order to prototype a real time system from high level specification. In many case, one allocated solution prototype is not so good to answer the environment changes around an embedded system. For this reason, an application implementation needs to have several prototypes with different performance levels in order to address the environment evolution. This paper gives an approach for rapid embedded system prototyping using a generic high level architectural model and existing prototyping platforms. A several architecture prototype are proposed to rapid converge to a limed architecture space solutions, thus the exploration process is accelerated and an efficient solution can be selected

One of the important problems of the analog signal processing is to design the filters which possess linear phase response in the frequency domain and at the same time the sharpness of the step response in the time domain. This paper presents theoretical concept of time-varying Butterworth filters with equalized group delay response. The compensation of the phase response is carried out with the aid of the allpass filter which is cascade-connected to the structure of the classic Butterworth filter. Time-varying coefficients were introduced to the phase-compensated filter structure for the purpose of minimization of the filter transient state. This paper contains simulation results of the proposed filters, solution of the undershoot problem, and comparison with the classic circuits

This work describes a proposal method for impulsive signal deconvolution. The method uses a simple one-layer neural-network configured for implementing an adaptive filter that models the unknown inverse impulse response of the propagation media. The Levenberg-Marquardt (LM) algorithm is used for finding the coefficients of the neural-network. The method has been tested on simulated channels, and on a mathematical model from a real cantilever beam. Results show that with proper training deconvolution can be achieved

Spatial processing with adaptive antenna array has shown real promise for substantial capacity enhancement in wireless communications. We propose in this paper a simple method to evaluate the probability of error in DS-CDMA receivers using a beamformer. We used a beamformer with adaptive antenna arrays followed by a RAKE receiver. Adaptive array can reduce the interference only when the directions of arrivals (DOAs) of the interferers are misaligned with the DOAs of the user of interest. The evaluation of bit error rate is counted differently according to the beam pattern and can provide good agreements with simulation results

In this two-part paper, a powerful and accurate method for sensorless control of permanent magnet brushless motors is explained. The method doesn't include any modification to the classical construction of such motors and can be easily integrated within the drive electronics. It is applicable to both motor types, i.e. those with sinusoidal or trapezoidal back EMF. The method is independent of excitation current profile. It is also virtually independent of system parameters. The back EMF waveform is extracted online using simple and integration-free algebraic expression through a newly proposed measurement setup. It is then used within the corrective phase of an extended Kalman filter (EKF). The method functionality is tested by simulation for both motor types and for different excitation current profiles. Simulation results show a good performance at very low speed. This part introduces the topics common to both motor types and presents in detail the application of the proposed method to the case of sinusoidal back EMF machine.

This paper introduces the application of neuro-fuzzy to control a three-phase uninterruptible power supply (UPS) for critical loads. The introduced controller incorporates adaptive neuro-fuzzy inference system (ANFIS) in rotating reference frame with three input variables and one control output variable. With this methodology, the problems caused by nonlinear loads and parameter variations of UPS system are solved. Moreover, it achieves high dynamic performance and accurate voltage regulation of the load with minimum total harmonics distortion (THD) and good steady-state characteristics. Simulation and experimental results on a three-phase prototype show effectiveness and advantages of the proposed controller especially under rectifier-type loading condition
