Actuator

As the name implies the operator is operating in a control loop. The loop control of a controller according to feedback from sensorsAnd receives the process values ​​and compares it to the process set point to reach the set point by commanding the actuator or operator to make the necessary changes to the process values ​​that lead to the set point. For example, in a control loop in the movement arm, a robot operates a device that, according to the values ​​that reach the controller of the device from the position sensor and the command it gives to a stepper motor, actually converts energy into controllable movement and causes force. In other words, the actuator in the field of motion control is a device that according to the command of the energy controller with pneumatic, electrical, hydraulic, electromechanical and ... mechanisms. By this definition, this type of actuators are used in industrial factories under the name of servo motors, step motors, pneumatic or hydraulic cylinders, which, like the muscles of the human body, have the task of moving and controlling movement. Are in charge. In the following, according to the nature of the work of the actuator or motion actuator, we can refer to linear models with linear and rotary or rotary, for example, the actuator required to open a linear rose or house door and to open or close a wing. If it is a ball valve or a butterfly, rotary models must be used. Also, in cases where high force is required, use hydraulic cylinders and pneumatic cylinders for high speed. In the following, according to the nature of the work of the actuator or motion actuator, we can refer to linear models with linear and rotary or rotary, for example, the actuator required to open a linear rose or house door and to open or close a wing.

With the initial definition of an actuator in a temperature control loop, a solid state relay or contactor or relay can act as an actuator or actuator, depending on the temperature increase or decrease (which is felt through the temperature sensor). ) And the controller command turns the heat source on or off. Note that if a gas or other fuel is used for heating, the actuator refers to the solenoid valve or valve control, which will reduce or increase the fuel.

The actuators are also mentioned in the control of the valve, which in fact is usually the upper part of a valve, which moves mechanically with the wind, ie pneumatically or electrically, depending on the type of valve.
