What Does a Field Adjuster Do?

The current level of industrial automation has become an important indicator for measuring the modernization level of various industries. At the same time, the development of control theory also went through three stages: classical control theory, modern control theory, and intelligent control theory. Typical examples of intelligent control are fuzzy fully automatic washing machines and the like. Automatic control systems can be divided into open-loop control systems and closed-loop control systems. A control system includes controllers, sensors, transmitters, actuators, input and output interfaces. The output of the controller is added to the controlled system through the output interface and the actuator; the controlled quantity of the control system is sent to the controller through the input interface through the sensor and the transmitter.

PID regulator

English: PID regulator

Different control systems have different sensors, transmitters, and actuators. such as

(1) First select a sufficiently short sampling period to allow the system to work;

(2) Only add the proportional control link until the system has a critical oscillation to the step response of the input, and note the proportional amplification factor and critical oscillation period at this time;

(3) Under certain control degree, the parameters of PID controller can be calculated by formula.

Abbreviation for proportional-integral-derivative regulator. Use the leading role of the proportional differentiation link to cancel the large inertia in the adjustment object, improve the accuracy, and speed up the dynamic response.
