Industrial Control System (ICS) is used to monitor and control critical infrastructures. Programmable logic controllers (PLCs) are major components of ICS, which are used to form automation system. It is important to protect PLCs from any attacks and undesired incidents. However, it is not easy to apply traditional tools and techniques to PLCs for security protection and forensics because of its unique...
This piece of work provides a hybrid power plant integrating a wind coupled with Permanent Magnet Synchronous Generator (PMSG), a super-capacitor (SC), a battery and a diesel engine (DE) set which operates without a grid connection. Each subsystem (e.g., wind, SC, battery, DE) has controlled through non-isolated PID/PI embedded controller power converters while the overall operation and power flow...
With the advancements in the field of science and technology; the hardware as well as the software (programming) techniques have also been advanced to meet the market requirements. The IEC 61131-3 is the third part of IEC 61131 standard; it is a standard for programming Industrial Control Systems like Programmable Logic Controller (PLC) etc. The IEC 61131- 3 specifies the syntax and semantics of two...
Aiming at low control accuracy in welding and dismounted the shunts by hand as well as too many subjective factors in manual recording data in the process of baking of aluminum reduction cell, we have designed a set of baking shunt auto control system. The system mainly contains two parts, baking shunt switch and the control system composed of Programming Logic Controller as well as industrial personal...
This study proposes a wireless remote control system for portable X-ray machine. This renovated system is based on C/S model, in which both Server and Client are portable computers, and the wireless network cards that suit the 802.11 n protocol are used for communications between Server and Client. In this designed system, the Client sends control commands to the Server through wireless network, and...
