Derivative of state '1' in block 'sunho/Inverse Dynamic/Integrator' at time 0.00014907010752590144 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)
I am using coding to make RR robotics arm SMC controller.
Please help me to solve this error.

Hi
You can try changing the solver to Variable-step ode15s (stiff/NDF).
Or refer the following link to resolve the issue :

Hope this helps!
