积分器的这个错误怎么解决？

Derivative of state '1' in block 'untitled/Subsystem/Integrator1' 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)

查了好多资料没找到解决方法

解决了吗楼主？

请问怎么解决啊？
