|
摘要
为了提高激光器稳态误差的调节能力,提出一种激光器稳态误差的智能自动调节技术。首先以激光器的输出功率、增益、输出效率等参量为约束指标,构建激光器稳态误差控制的约束参量模型,确定如果采用参数辨识识别方法对激光器参数进行智能控制,引入积分项进行稳态跟踪,并采用智能调节技术对稳态误差自动调节,提高激光器控制输出的鲁棒性,最后采用仿真实验分析其性。仿真结果表明,本文方法的激光器稳态误差控制精度高,提高了激光器输出质量。
In order to improve the adjustment ability of laser steady-state error,an intelligent automatic adjustment technology for laser steady-state error is proposed. The constraint parameter model of the laser steady-state error control is constructed by using the output power,gain and output efficiency as the constraint parameters. It is determined that if the parameter identification and recognition method is used to control the laser parameters intelligently,the integral term is introduced for steady state tracking,and the intelligent adjustment technology is used for the steady-state error. The difference automatic adjustment improves the robustness of the output of the laser control. Finally,the simulation experiment is used to analyze its property. The simulation results show that the accuracy of laser error control is high and the output quality of laser is improved.
