| 摘 要： | 轮轨粘着牵引力是决定电力机车牵引性能的重要参量，但不能被直接检测到。应用状态观测器的方法，以可检测量（牵引电动机电流和转速）为输入量，通过观测器输出可得到轮轨间粘着力的动态估计量，此方法可用于对电力机车动轮粘着牵引力实现在线动态检测。文中推导出观测器状态方程并给出模拟电路图。经初步试验，结果是满意的。

| Abstract: | Wheel rail adhesive power is an important variable deciding tractive performance of electric locomotives,but it is not a directly detectable variable.With state observers and current and rotating speed of the tractive motor taken as input of the tractive force observer,the estimated dynamic value of wheel rail adhesive power can be obtained from the observer output.Therefore,on line detecting adhesive power of electric locomotive is realized.The state equations for the tractive force observer are derived,and the analogous circuits are also given. The experimental results are satisfactory. |
