摘要
应用Origin拟合软件,利用阶跃法推导出近似e指数函数作为拟合函数来求取电机系统的机械时间常数,并进行了实验验证。实验分析证明,应用Origin拟合可获得可信度高达97%左右的参数辨识,其拟合误差小于0.1。当动态靶标转速为36°/s时,控制系统跟踪最大脱靶量从90″降到了70″。
In Origin,similar exponential function derived with step method is taken as the fitting function to obtain the mechanical time constant for the computer control system.Experimental results show that the accuracy rate of the parameter identification is up to 96% with the error less than 0.1.When the dynamic target speed is 36°/s,the tracking error of the computer control system decreases from 90 ＂to 70＂.
