- Use 0.000000001 or so instead of 0 in Integrator initial condition box. Try reducing or increasing number of zeroes until your model runs fine.
- Use a delay block in front of "division" block.
Derivative input is Inf

Hi,
I face a Simulink problem at the input of the integration block, which is:
Derivative input 1 of 'test_ahmed/Integrator' at time 0.003375 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)
However,the input of the integration block is not infinity according the scope.
The model belongs to sliding mode control of biped robot in single support phase.
attached with the message simulink model..
Thank you!

I have a similiar error, I guess: https://www.mathworks.com/matlabcentral/answers/334702-solar-pv-panel-simulink-solver-error
