This paper presents a practical framework to bring the cyber-physical block diagram models, such as Ptolemy, to the practice of industrial automation. Cyber-Physical Component (CPC) architecture is suggested. CPC aims at the improvement of design, verification and validation practices in automation of Smart Grid. IEC 61499 standard is used as a basis for this architecture. This architecture addresses...
PLC is introduced into the ECM control system, which increases the ability, stability and automation of the device. But with the increasing number of peripheral equipments, it is harder to maintain the system. In the paper, ECM control system is proposed. The system includes three parts: upper system based on PC, PLC control system and servo control system. The three parts communicate with each other...
With the rapid development of information technology, the computer has been more and more important in our lives. Especially it makes our working, learning and entertainments, and even consumptions dependent on the computer increasingly because of the popularity of network. However, the computer has brought us a lot of convenience, while it also makes us face with a variety of security risks. Computer...
This paper develops and designs a fuzzy PID controller using PLC for a setpoint pressure control problem in the collecting main pressure system. The controller objective is to make the collecting pressure attain to the desired techniques range. The collecting main pressure control system uses programmable logic controllers (PLCs) to implement the pressure control action. The proposed fuzzy controller...
This paper develops a fuzzy network control system for the collecting main pressure control. This control system is connected via Profibus-DP for the real-time communication in the control system. The collecting main pressure system is a multi-variables, nonlinear and heavy coupling system. The coupling problem is the major difficulty in the collecting main pressures system. The fuzzy forward decoupling...
Event detection has become an important research issue in the decision making process of dynamic systems where one should be able to comprehend the situation in order to make an appropriate decision for future development. And machine intelligence is required to provide a solution for automated event detection. In this paper we propose a hybrid fuzzy logic system that has been used for detecting event,...
A microprocessor-based touch-screen Human-Machine Interface (HMI) and Programmable Logic Controller (PLC) standard libraries are applied to construct models for creating supervisory control software. This software, in turn, is developed and presented for the Graphical User Interface (GUI) functions used in agriculture wastes reuses process of steam-boiling pretreated to become efficiently produce...
Based on automation project of Daping ore-dressing plant in Yunnan province,the application of fuzzy control to the ore-giving system of grinding classification is introduced. The system uses scheme of combining fuzzy control with PID control. Fuzzy control of ore-giving setting value is realized by measuring mill current and adopting two-dimension fuzzy controller. Fuzzy control algorithm and control...
This study investigates the effect of using pH as aeration control parameter on nitrogen removal via simultaneous nitrification and denitrification (SND) in a 10 L acetate-fed SBR. The reactor is operated continuously with quickly terminating the aerobic phase after ammonium depletion, according "ammonia valley" in pH profiles. The results indicate using pH as control parameter on nitrogen...
To solve nonlinear multi-objective dynamic optimization problem originates from process control, a modified frame of dynamic modular multivariable controller based on lexicographic optimization strategy is proposed, which had control modules with different priorities. A modified one-step fast nonlinear predictive control algorithm is used to solve control input in every module. Strategy of the selection...
