我做了个交流异步电机模型，运行的时候一个积分环节出错了。错误信息：Derivative input 1 of 'acmotor001/Subsystem2/Integrator' at time 0.001 is Inf or NaN. Stopping simulation. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances).在仿真环境设置里面减小min step 还是不行。希望大家指点迷津！[local]1[/local]
Derivative input 1 of 'zongwanfei/BG/baiC/Integrator' at time 0.003359403682830997 is Inf or NaN. Stopping simulation. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances).一楼的朋友，向我的模型也是，老是出现这样的错误——而且在这里咨询了有进10天了，也没能得到解决。真的希望能有个高手帮帮忙，如果是改变积分的话，我的模型很大，难度也大——再说了，如果是把积分变做求导，那还用积分这个模块干什么呢？？期待有人能解决，如果一楼的解决了，也望能诉我下，QQ93644311，邮箱afei8233@yahoo.com.cn
This is an integration error. When a 0 is inputted into the initial conditions box in the
block labeled “integrator” the output is infinite. To solve this problem input
0.0000000000000000001 in the initial conditions box.
