In academic circles, there is no specific algorithm formally defined as “advanced control.” Rather, the term broadly refers to any control strategy beyond the conventional PID (Proportional-Integral-Derivative) framework. In industrial practice, however, “advanced control” most commonly refers to Model Predictive Control (MPC). This article aims to revisit and clarify some common perceptions around advanced control […]

Implementing Safety Integrity Level 1 (SIL1) interlocks in a Distributed Control System (DCS) is a viable approach under specific conditions. SIL1, defined by the international standards IEC 61508 and IEC 61511, represents the lowest level of safety integrity and is often used for processes where the risk reduction required is moderate. However, achieving compliance requires

In the process of selecting a frequency converter, the concepts of light load and heavy load are crucial. Proper understanding and distinction between these two load types are essential for choosing the right frequency converter. What is Light Load? In the electrical industry, light load refers to a situation where the electrical control components, under

SCADA (Supervisory Control and Data Acquisition) systems play a critical role in modern industrial automation and control. These systems provide organizations with the tools to monitor, analyze, and control various industrial processes remotely or on-site. Widely utilized across industries such as energy, water management, manufacturing, and transportation, SCADA systems ensure operational efficiency, safety, and data-driven

Problem Definition:Oscillation in control systems typically indicates a problem in the control loop. In the case of level control, we are dealing with oscillation caused by improper PID parameters and insufficient material input. Specifically, in a level control system where the discharge flow is used to control the liquid level, inadequate material input coupled with

Introduction In industrial and electronic applications, voltage and current signals are transmitted through conductors in two distinct forms: common mode and differential mode. Various electrical devices, such as power lines, communication cables, and instrument connections, use at least two conductors to transmit signals. Additionally, a third conductor, known as the ground wire, is often present.

What is Overload? In both power grids and everyday electrical devices, every piece of electrical equipment operates within a specified rated power. When the power drawn by the equipment exceeds this rated power, the condition is referred to as an overload. Similarly, the mechanisms implemented to safeguard against such excessive power consumption are termed overload

Virtual serial ports (VSPs) are software-based representations of physical serial ports that enable communication between applications and devices without requiring actual hardware. They provide a way to simulate serial communication, facilitating development, testing, and integration in various fields. This article delves into the uses, benefits, and applications of virtual serial ports in detail. What is

Understanding Analog Signals in PLC Systems In industrial automation, Programmable Logic Controllers (PLCs) play a crucial role in monitoring and controlling processes. However, most real-world signals, such as temperature, pressure, and flow rate, are continuous analog signals. PLCs, on the other hand, operate using digital signals (binary 0s and 1s). This means that analog signals

1. Routine Maintenance of the DCS System Proper maintenance of the Distributed Control System (DCS) is crucial to ensuring system stability, reliability, and efficiency. Regular maintenance reduces the risk of system failure and enhances operational safety. 1.1 Key Routine Maintenance Tasks Maintaining a Stable Environment Ensure air conditioning systems are functioning correctly to maintain a
