Hi Shubham,
As per my understanding, you are getting the following error:
Nonlinear iteration is not converging with step size reduced to hmin (1.07322E-15) at time 0.302084. Try reducing the minimum step size and/or relax the relative error tolerance.
Please refer to the below pointers for more information about the same:
- This error message means that one of the signals in your model is diverging to plus or minus infinity or is otherwise changing too rapidly based on the solver settings.
- This means that with these settings, the solver is unstable for the equations represented by the model. It is a stiff model that requires more stability for the solver.
- One way to resolve this error is to reduce the maximum order for your model.
- You can refer to the following documentation link for more information on how to reduce the order of a model: https://www.mathworks.com/help/releases/R2022a/ident/ug/use-state-space-estimation-to-reduce-model-order.html
