What is motion control?
Motion control (MC) is a branch of automation, also called electric drag control. Most of its power sources are based on electric motors.
In other words, motion control is actually based on electric motors to control changes in physical quantities such as angular displacement, speed, and torque.
The application of motion control in the field of robots and CNC machine tools is more complex than that in special-purpose machines because the latter's motion form is simpler and is often called general motion control (GMC). Motion control is widely used in the packaging, printing, textile and assembly industries.
Motion control is actually based on electric motors, and the electric motors here refer to servo motors; if only one servo motor is used in a set of stand-alone equipment, in this case it will focus more on the control of the motor, such as position, speed, Torque control; in this example, the control of a single motor is only a part of motion control.
Motion control is mainly for products. It can be said to be a motion control system. The system as a whole includes machinery (motors are just spare parts in machinery), electrical, software, etc. It controls and manages the position and speed of mechanical moving parts in real time. , so that it can be transformed into the desired mechanical motion control according to the predetermined control scheme.
There are many kinds of motion control systems, but from the basic structure, the hardware of a typical modern motion control system mainly consists of: host computer, motion controller, power drive device, motor, actuator and sensor feedback detection device.
What is automated process control?
The principle of automated process control is to use PLC controllers to collect sensor feedback data, and after analyzing and processing these data, adjust, optimize and control various equipment to improve production efficiency.
The objects it controls are generally various types of water pumps, fans, electric valves, etc. The entire system generally consists of PLC control cabinet, power distribution cabinet, control program, various sensors, configuration software, monitoring system, etc.
Process automation is generally used in environmental protection industries such as sewage and exhaust gas treatment, and energy-saving industries. It intelligently adjusts various load equipment in industrial production to ensure that they operate at their best to achieve energy saving. Mainly used in the field of traditional industrial automation, it is a large system control with many control objects, such as a production line.
