Control is the process of regulating or manipulating a system or a machine using feedback mechanisms, such as controllers, correction elements, etc.


  • What is the difference between open-loop and closed-loop control systems?



Open-loop control systems are systems that do not use feedback to adjust their output according to the desired value. Closed-loop control systems are systems that use feedback to compare their output with the desired value and adjust it accordingly.


  • What is PID control?



PID control is a type of control that uses proportional, derivative and integral control laws to achieve a desired output. PID stands for proportional-integral-derivative.


  • What is a PLC?



A PLC is a programmable logic controller, which is a device that can be programmed using ladder logic to perform various control tasks, such as motor control, traffic light control, conveyor belt control, etc.
