There are many types of industrial controllers, which can be classified into the following categories according to different classification standards:
Classify by control object
Unidirectional motor controller: mainly used to control the start, stop, and speed regulation of unidirectional motors.
Bidirectional motor controller: used to control the forward and reverse rotation and speed regulation of bidirectional motors.
Pneumatic controller: used in pneumatic systems to control pneumatic actuators by controlling air pressure.
Hydraulic controller: used in hydraulic systems to control hydraulic actuators by controlling oil pressure.
PLC (Programmable Logic Controller): A universal industrial controller with programmability and real-time performance, suitable for various industrial automation applications.
Classified by control method
Open loop controller: Control based solely on input signals, without considering feedback from output signals.
Closed loop controller: Comparing and adjusting based on feedback from input and output signals to achieve more precise control.
Classified by Function
Counter: Used for counting and timing functions, commonly used for quantity statistics and timing control in the production process.
Timer: Used to implement timed control, such as timed start, stop, and switch.
Proportional controller: Adjust the output signal proportionally based on the size of the input signal.
PID controller: A commonly used closed-loop controller that achieves precise control of a system through proportional, integral, and derivative operations.
Other types
CNC (Numerical Control): Used for controlling machine tools and processing equipment to achieve high-precision workpiece processing.
DCS (Distributed Control System): Used for controlling large-scale process control systems, it has the characteristics of distributed and modular.
PAC (Programmable Automation Controller): Combining the characteristics of PLC and industrial computer, it has more advanced computing and communication capabilities.
SCADA (Supervisory Control and Data Acquisition System): A software platform used for monitoring and controlling distributed systems, with data acquisition, remote control, and alarm functions.
IPC (Industrial Control Computer): A high-performance industrial controller suitable for scenarios that require processing large amounts of data and performing complex control algorithms.
Embedded controller: small size, low power consumption, high integration, suitable for scenarios with strict requirements for controller size and power consumption.
