基于最小二乘法的电梯平衡系数曲线拟合

Curve-fitting of the Elevator Balance Coefficient Based on the Least Square Method

目前电梯平衡系数曲线的绘制大都采用手工描点画图的方式，这种方式既费时又存在较大人为误差。这里提出一种基于最小二乘法得出运行电流与电梯负载之间的函数关系I=f（P），从而进行曲线拟合的方法，利用这种拟合方法可实现利用计算机程序绘制电梯平衡系数曲线。

Now the curves of the elevator balance coefficient are drawn up by hand, which it causes manual error and takes a lot work. This paper puts forward a method of curve-fitting with the function between the elevator load and its running current （I=f （P）） based on the least square method, and to practice this curve be draw up by computer.
