The article is concerned with the issues of practical utilization controllers for automation in various technical fields as example Mitsubishi MELSEC FX1N and FX3U series. Any task, which requires electrical control devices, easy to solve by means usage programmable logic controllers. By using software programming package GX Developer, user has possibility program controller or input changes in...

in this article, a speed control of dc motor is designed and illustrated using fuzzy logic-based programmable logic controller (plc). the dc motor is an attractive part of electrical equipment in many industrial applications requiring variable speed and load specifications due to its ease of controllability. the designed system is consisted of three main parts including programmable logic contr...

Many teaching institutions worldwide have decided to work firmly in distance learning applications. In this frame, remote laboratories enable the intensive use of the university devices and ease the work of professors and students. The present work introduces different platforms to be used in industrial automation practises, developed in Barcelona, Manaus and Santiago de Cuba. The platforms are...

In the article we propose a new design method for microprogrammed controllers. The traditional structure is improved by modifying internal modules and connections. Such a solution allows reducing the total number of logic elements needed for implementation in programmable structures, especially Field Programmable Gate Arrays (FPGAs). Detailed results of experiments show that on the average the ...

The author in his research has focused on real time digital controllers which traditionally are designed as finite state machines or Petri nets. Such controllers can be effectively modelled with some subset of UML statecharts and next can directly be implemented in programmable logic devices (for example FPGA). This transformation is being realized by a system known as HiCoS (abbreviation comes...

This paper presents a design approach intended for the modeling and synthesis of discrete-event modules of hybrid controllers by combining a model of computation and a soft computing synthesis approach. The model of computation is based on coloured Petri nets (CPNs) and the soft computing method uses fuzzy logic. The design approach converts Petri net models into their equivalent fuzzy sets for...

| We present an algorithm for synthesising real-time controllers speciied in a subset of the interval temporal logic Duration Calculus. The synthesised controllers are given in terms of PLC-Automata, which are an abstract description of programs of polling machines. PLC-Automata can be implemented directly on Programmable Logic Controllers (PLCs), a special kind of polling real-time controllers...

This work is devoted to the development of an automated transfer switch (ATS) for 6/0.4 kV substation. The relevant due introduction automation and replacement electromechanical equipment with microprocessor devices in power systems. At lower (field) level, driven by use programmable logic controllers (PLCs) various smart sensors. possibility using modular PLC systems considered. Developed are ...
