What is process control? Answer: It refers to the use of automated tools such as measuring instruments, actuators, and computers, along with control theory, based on the characteristics of industrial production processes, in order to design control systems for these processes and achieve automation in industrial production.
Process control in industry refers to automatic control that uses process parameters such as temperature, pressure, flow rate, liquid level, and composition as the variables to be controlled. Process control, also known as real-time control, involves computers collecting and monitoring data in real time, and then rapidly performing automatic control and adjustment of the controlled system to achieve optimal results; this is applied in areas such as the control of CNC machines and production lines.
Automatic control achieved through a pre-programmed fixed procedure. It is widely used to control various production and processing processes.
An automatic control system that uses the parameters characterizing the production process as the variables to be controlled, in order to bring them close to a specified value or keep them within a given range

Answer: A process control system is an automatic control system that uses the parameters characterizing a production process as the variables to be controlled, in order to bring them close to a specified value or keep them within a given range. Process control is widely used in industries such as petroleum, chemicals, power, and metallurgy. In the 1950s, process control was primarily used to maintain certain parameters within a production process constant, thereby ensuring stable output and quality. In the 1960s, with the emergence of various instrument panels and patrol testing devices, process control began to transition toward centralized monitoring, operation, and control. In the 1970s, multi-level computer control systems that combined process control optimization with management scheduling automation emerged. An automatic control system in which the parameters characterizing the production process are used as the controlled variables to bring them close to a given value or keep them within a specified range. Here, “process” refers to the processes of interaction and transformation of matter and energy that take place within production plants or equipment. For example, the generation of steam in boilers, the separation of crude oil in distillation towers, etc. The main parameters characterizing the process include temperature, pressure, flow rate, liquid level, composition, concentration, etc. By controlling the process parameters, it is possible to increase the output of products, improve their quality, and reduce energy consumption during the production process.
Automated tools such as measuring instruments, actuators, and computers are employed, along with control theory, to design control systems for industrial production processes, thereby achieving automation in these processes.
