Derivative of state '1' in block 'a1011/Plant/Integrator' at time 0.0 is not finite. The simulation will be stopped. 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)
Component: Simulink | Category: Block error

请问楼主这个问题是怎么解决的？

检查fun函数，是否有除零操作
