Hi @AAKASH
The error message you are facing in Simulink suggests that there's an algebraic loop involving the block “akash/Sum5” that Simulink is unable to resolve. Algebraic loops happen when there's a circular dependency between blocks that Simulink cannot solve directly.
To resolve the issue kindly utilise following resource:

I hope this will be helpful.
