simulink出现奇点问题怎么解决

Question

An error occurred while running the simulation and the simulation was terminated
Caused by:
Algebraic state in algebraic loop containing 'H/Divide5' computed at time 0.00043000000000000004 is Inf or NaN. There may be a singularity in the solution. If the model is correct, try reducing the step size (either by reducing th

e fixed step size or by tightening the error tolerances)

simulink里面遇到这种奇点问题该怎么解决啊？

Answer 1

出现这个问题最可能的情况是有代数环，解决的办法是模型化简消除代数环，或者在反馈回路上增加memory或unit delay模块来近似消除代数环。
