The aim of this work is to evaluate the effectiveness of a Simple Tuning algorithm applied on a Fuzzy Pulse Width Modulation controller in a real situation with DC gear motors. The fuzzy logic model proposed to control motor’s no-load speed consists in 25 rules based on Mamdani Fuzzy Inference System. A hardware implementation and an interface are designed for controlling the plant. In addition...

The main topic of this paper is to examine the impact on induction machine magnetic noise of a new stator magnetic circuit design. This new design was developed in order to increase AC machine energetic performance by assembling non-segmented shifted grainoriented steel sheets which make it possible to reduce iron losses. Experimental results on induction machine efficiency increase are present...

The optimal torque control of a synchronous machine is a classical problem. This paper presents an alternative to SVM (Space Vector Modulation which belongs to PWM approaches) based upon direct boolean control. The result is a predictive method allowing an optimal torque control of the synchronous machine. A comparison between both approaches will be proposed . Copyright  2002 IFAC

This article describes software application, that generates voltage pulses. The input commands are Musical Instruments digital interface messages. As already mentioned the name of it is the interface that is used primarily to control musical instruments through the computer. But this software is mentioned for all electridcal device without any communication protocol. E.g. DMX protocol and other...

Pulse-width modulation (PWM) is the basis for control in power electronics. The theoretically zero rise and fall time of an ideal PWM waveform represents a preferred way of driving modern semiconductor power devices. With the exception of some resonant converters, the vast majority of power electronic circuits are controlled by PWM signals of various forms. The rapid rising and falling edges en...

MultiLevel Inverter (MLI) is used in applications that need high voltage and high current especially for Flexible AC Transmission System (FACTS) controllers. The topologies of multilevel inverter have several advantages such as lower Total Harmonic Distortion (THD), lower ElectroMagnetic Interference (EMI) generation and high output voltage. The main feature of Modular Structured Multilevel Inv...

A new three-level ac–dc single-stage converter that can operate with standard phase-shift pulse width modulation is proposed in this letter. In this letter, the operation of the converter is explained, and its feasibility is confirmed with experimental results obtained from a prototype converter. Finally, the efficiency of the new converter is compared with that of a previously proposed convert...
