What is PID controller and its applications
PID controller, also known as Proportional Integral Derivative Controller, is an extremely important control algorithm in the field
of industrial control. It consists of three basic parts: proportional unit (P), integral unit (I), and differential unit (D), and precise control
of the controlled object is achieved by adjusting the parameters (Kp, Ki, Kd) of these three parts.
The principle of PID controller
The core idea of PID controller is to predict the future state based on the current state (i.e. deviation) and past state (i.e. integral
and derivative of deviation) of the system, and adjust the control quantity accordingly, so that the
system output can quickly and accurately track the set value. Specifically:
Proportional (P) control: Generate corresponding control effects based on the size of the error, and the larger the error,
the stronger the control effect. Proportional control can quickly respond to errors and reduce steady-state errors,
but cannot eliminate steady-state errors.
Integral (I) control: Integrating errors to eliminate static errors (i.e. steady-state errors). As long as there is an error,
the integral controller continuously accumulates the output control quantity until the error is zero. Excessive integration
can lead to increased overshoot and even oscillation in the system.
Differential (D) control: Reflecting the trend of error changes and generating control effects in advance. Differential
control can reduce overshoot, overcome oscillations, improve system stability, and accelerate the dynamic response speed of the system.
