This system, developed for integrating into automated production lines, is used in rotary welding of plastic components, offering fast and flexible processing.

It is suitable for applications requiring moderate welding speeds, and uses a pyrometer to collect data and provide real-time adjustment of the laser power output.

The basic principles of PID control

PID control is a feedback control algorithm whose core principle is to calculate the control signal through three components: proportional, integral, and derivative.

Specifically:

Proportional (P) control: Directly reflects the error signal of the control system proportionally, used to reduce system error.

Integral (I) control: Integrates the error to eliminate steady-state error, but may reduce the system's response speed.

Derivative (D) control: Differentiates the error to predict the trend of error change, reducing overshoot and oscillation, and accelerating the system's response speed.

Mathematical expressions and application scenarios of PID control.

Here, u(t) is the control variable, e(t) is the error signal, and Kp, Ki, and Kd are the proportional, integral, and derivative coefficients, respectively.

PID control is widely used in various industrial process control applications, such as the control of temperature, pressure, flow rate, and liquid level.

Due to its simple algorithm, good robustness, and high reliability, PID control has become one of the main technologies in industrial control.
