In order to improve the accuracy of laser measurement,the physical parameters of the laser are adaptively adjusted and optimized. The optimization technique of high precision laser physical parameters based on servo inertia parameter adjustment and instantaneous global optimization is proposed,and the constrained parameter model of high precision laser physical parameter optimization is constructed,which can be used for rotational inertia,load and ranging error. The damping and other parameters are the control constraint parameters. The fuzzy inference technique is used to adaptively optimize the physical parameters of the high precision laser. The output oscillation is suppressed according to the overshoot error of the laser,and the accurate measuring ability of the laser is improved. Using servo inertia parameters as independent variables,adaptive parameters are adjusted to achieve fuzzy matching and global optimization of high precision laser physical parameters. The simulation results show that this method is used to optimize laser physical parameters. It has a good ability of adjusting parameters adaptively,improves the accuracy of laser measurement,reduces the error of parameter calculation,and meets the requirements of high precision calculation and measurement of laser.
