Cannot solve algebraic loop involving 'Model_Test/Controller' because it consists of blocks that cannot be assigned algebraic variables, such as blocks with discrete-valued outputs, blocks with non-double or complex outputs, Stateflow blocks, or nonvirtual subsystems. Consider breaking the algebraic loop.
Component:Simulink | Category:Model error
Algebraic loop error with 'Model_Test/ Model '
Component:Simulink | Category:Model error
Algebraic loop error with 'Model_Test/Controller'
How to fix this error ?

Hi @FAIZ UL HASSAN, try to add a Unit delay block.

Initial condition for output graph to start from (non zero value) and yes I tried ode15s (stiff/NDF) with different values of relative and absolute tolerance. I already added unit delay for algebraic loop.
