摘　　要：由于激光器的温度特性具有显著的时变性、非线性和强耦合性,传统控制方法很难满足精确的控制需求。针对上述问题,研究一种激光器温度非线性自抗扰控制方法。该方法利用激光器内部封装的热敏电阻采集激光器实时温度,计算与理想温度之间的实时误差。以误差为输入,利用非线性自抗扰控制器计算得到激光器温度实时控制信号,完成精确控制。结果表明:所研究方法控制下,变异系数相对更小,这表明方法在控制效果上表现更好,能够更好地控制激光器温度更接近理想温度,使温度更加稳定和可靠。Due to the significant temporal variability,nonlinearity,and strong coupling of laser temperature characteristics,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 thermistor encapsulated inside the laser to collect real-time temperature of the laser and calculate the real-time error between it and the ideal temperature.Using error as input,a nonlinear self disturbance rejection controller is used to calculate 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 better in control effect and can better control the laser temperature to be closer to the ideal temperature,making the temperature more stable and reliable.
