What is automatic process control?

The plc controller is used to collect the data fed back by the sensor, and after analyzing and processing these data, various equipments are adjusted, optimized and controlled to improve the production efficiency. Its control objects are generally all kinds of pumps, fans, electric valves and so on.

Process automation is generally used in environmental protection industries, such as sewage and waste gas treatment, and energy-saving industries, to intelligently adjust all kinds of load equipment in industrial production to ensure that it runs in the best state, so as to achieve the purpose of energy saving.

The whole system is generally composed of plc control cabinet, power distribution cabinet, control program, various sensors, configuration software, monitoring system and so on.

Process control is mainly used in the field of traditional industrial automation. It is a large-scale system control with many control objects, such as a production line.

From the point of view, the primary concern of automatic process control (servo motor here) is to control one or more parameters of a single motor to reach a given value. The primary concern of motion control is to harmonize multiple motors and finish the specified motion (composition of track and composition of speed), with more emphasis on track planning, speed planning and kinematic transformation; For example, the XYZ axis motor should be harmonious in the CNC machine tool, and the interpolation action should be finished.
