If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances) 解决:1)加avoid division zero模块,避免过零发散。点击wind turbine模块,然后点击Mask-look under mask-模型里出现后复制即可。 2)减少步长或者设置为固定步长,缩小误差容限,或者设置start ...
I am using a simple model in Simulink in which I use a division on two input values using a 'Divide' block. During my simulation, there might be a zero value fed to the denominator of the 'Divide' block. This often causes a warning, an error...
解决：1）加avoid division zero模块，避免过零发散。点击wind turbine模块，然后点击Mask-look under mask-模型里出现后复制即可。2）减少步长或者设置为固定步长，缩小误差容限，或者设置start time大于0。点击ctrl+E弹出configuration parements进行设置。3）如果上述方法都不能解决问题，仍然报错，就需要考...

In the execution paths where the ÷ input equals zero, the division operation results in a Division by zero error. To resolve this error, check that the ÷ input is not zero. For instance, use the If (Simulink) block and put the Divide block in an If Action Subsystem (Simulink). ...

To avoid the small time steps and long simulations associated with these situations, Simulink uses zero-crossing detection to accurately locate such discontinuities. For systems that exhibit frequent fluctuation betweens modes of operation—a phenomenon known aschattering—this zero-crossing detection can ...
