Research on nonlinear autodisturbance rejection control method for laser temperature
Due to the significant temporal variability,nonlinearity,and strong coupling of laser temperature char-acteristics,traditional control methods are difficult to meet precise control requirements.To address the above issues,a nonlinear self disturbance rejection control method for laser temperature is studied.This method utilizes the ther-mistor encapsulated inside the laser to collect real-time temperature of the laser and calculate the real-time error be-tween it and the ideal temperature.Using error as input,a nonlinear self disturbance rejection controller is used to cal-culate the real-time control signal of the laser temperature,achieving precise control.The results show that under the control of the studied method,the coefficient of variation is relatively smaller,indicating that the method performs bet-ter in control effect and can better control the laser temperature to be closer to the ideal temperature,making the tem-perature more stable and reliable.
