Control techniques
Schneider's technical papers, Forums and groups.
Here are some sites which present a blend of informations as different as industrial automation and control, instrumentation, data processing or communication and electrical engineering, all in one directory.
Fuzzy logic, Detection and sensors technologies, Motors and drives, Electrical engineering, Safety.
The Schneider Electric company offers a lot of articles in its well known technical papers intended to the industrial world.
They concern control techniques, instrumentation matter, high, middle and low voltage matters, motorization and electrical engineering.
These selected articles concern, by far or by near, the control engineers.
This paper about the « fuzzy logic » introduces the theory and the basics, and how this technique can be applied to process control and to industrial control in general.
After a short historic, the authors show how interesting can be the usage of the fuzzy logic to control the production. Then, they introduce the theory of the « fuzzy logic ».
They tackle the notions of membership, of operators, of inference rules, of fuzzification / defuzzification and more.
The whole is illustrated by a didactic industrial application example.
Next, we can read considerations about the necessity and the utility by employing the fuzzy logic in the industry, which methodology to use for designing an industrial application, how to operate it and how to use it.
Finally, the authors introduce what are the technologies to take in consideration and what are the potential applications. They finish by showing a few concrete realizations in the industry.
François CHEVRIE, François GUELY - www.se.com
This publication introduces the fundamental notions about detection.
First, the authors define the function of detection, the functionalities of the detection, and they introduce the different technologies which can be met.
Then, they detail the different kind of sensors and their technologies : inductive proximity sensors, capacitive sensors, photoelectric sensors, ultrasonic sensors, RFID detection, machine vision and image processing, optical encoders, pressure switches and vacuum switches.
Each chapter is very well illustrated, and describes one sensor with its associated technology. Within one chapter, we can find the principles of the measurement with its equations, the different implementations of the sensor, the parameters which have influences on, and finally its application areas.

Daniel CLÉNET.
The redactor develops what are the advantages of driving the motors using inverters.
The speed drives can low inrush currents and avoid mechanical shocks while they allow to control the motor speed, the motor acceleration rate and the motor deceleration rate.
The author presents the main operating modes and the different types of electronics drives, what are the available architectures in usage, how work the variable speed drives for direct current ( DC ) motor and the frequency inverters for asynchronous motors and other functions they can offers.
Étienne GAUCHERON.
First, you will find a short resume introducing the various type of electric motors and how they can operate.
Then you will read the technical and operating characteristics of asynchronous motors, especially the starting controllers, the speed controllers and the different braking method we can encounter.
The objective of the author is to give the reader a solid knowledge, helping him to well understand all the problems in relation with motor control and protection.
Jean-Yves BLANC.
The high voltage motors are generally used when a power exceeding 100 kW is needed.
Jean-Yves BLANC presents here the different starting processes for such motors, how they can be controlled and monitored, and what are the different techniques to protect them.
Jacques SCHONEK and Yves NEBON.
After introducing what are the frequency converters, the authors lists the devices available to protect them against overcurrents.
Then they explain how to protect people, and which protection devices has to be used with motor drives.
Finally, they present specific events, such as high-frequency leakage currents, leakage currents while powering up and more, and how to prevent malfunctions.
Jean-Noël FIORINA.
The author demonstrates here that inverters are delivering a true sinusoidal output signal, even for non linear loads, at the opposite of uninterrupted power supply ( UPS ).

Jacques DELABALLE.
After introducing the electromagnetic compatibility, what it is, why we need it and why the theory is so complex, the author presents what are the sources of the electromagnetic fields.
He explains then which systems they can disturb by coupling, the different coupling modes which can interact and which systems are sensible to the electromagnetic fields.
Finally he shows what can be the consequences of electromagnetic disturbances and what are the possibilities to prevent malfunctioning due to electromagnetic interactions.
Roland CALVAS.
What are the origins of the electric disturbances and what are the resulting risks ?
In parallel with the document above, it is question of electromagnetic compatibility ( EMC ) too, particularly in the industrial world.
Roland CALVAS develops the different kind of disturbances we can meet such as amplitude disturbances, sine waves disturbances, multi-phases specific disturbance and electromagnetic disturbances.
Nicolas CHAUMIER.
The purpose of this technical paper is about energy saving in any kind of building.
It is before all a methodology intended for preliminary studies, which guide you by exploring what can be the elements contributing to energy saving, and how to select them according to a specific installation.
After a presentation of the various electric and electromagnetic fields disturbances, the authors present how to prevent them.
Particularly important in the industry for effective and safe networking, such as electronic usages ( PLC, controllers, computers, network switches, instruments, sensors, drives, inverters and many other electronic devices we can use ), this paper lists what can be the electric disturbances on the low voltage network, and what are the different earthing systems we can install to prevent them.
Emmanuel CABAU
First, the author defines what are the dependability and its components ( maintainability, safety, reliability and safety ).
Then Emmanuel CABAU details how important is the dependability for the automated installations, what are its characteristics and what are the potential defects ?
Finally, he presents different methods and techniques to take in account while designing dependable installations and systems.
Sylvie LOGIACO
The author explains us how a dependability study is carried out, with some examples and introducing to some useful tools.
Jean PASTEAU
The author defines here the standards of the degrees of protection and why we need a standard. Then he defines the international protection ( IP ) code and the IK codes ( an addition to the IP code ).
