How can I resolve an electrical/Solver Configuration' error

Hello,

This model has been tested in parts and runs until I add the signal to the input of the PID. I get the following errors.

Due to some optimizations, Simulink may not be able to highlight the section of the loop containing 'electrical/PID Controller (2DOF)/D Gain/Internal Parameters'. [6 similar]

Component:Simulink | Category:Block warning 'electrical/Solver Configuration' or the model referenced by it contains a block that updates persistent or state variables while computing outputs and is not supported in an algebraic loop. It is in an algebraic loop with the following blocks.

Component:Simulink | Category:Model error Input ports (1, 2) of 'electrical/Solver Configuration' are involved in the loop.

Component:Simulink | Category:Model error Input ports (2) of 'electrical/PID Controller (2DOF)/Sum3' are involved in the loop.

Component:Simulink | Category:Model error Input ports (1) of 'electrical/PID Controller (2DOF)/D Gain/Internal Parameters/Derivative Gain' are involved in the loop.

Component:Simulink | Category:Model error Input ports (1) of 'electrical/PID Controller (2DOF)/Filter/Cont. Filter/SumD' are involved in the loop.

Component:Simulink | Category:Model error Input ports (1) of 'electrical/PID Controller (2DOF)/N Gain/Internal Parameters/Filter Coefficient' are involved in the loop.

Component:Simulink | Category:Model error Input ports (1) of 'electrical/PID Controller (2DOF)/Parallel P Gain/Internal Parameters/Proportional Gain' are involved in the loop.

Component:Simulink | Category:Model error Input ports (1, 3) of 'electrical/PID Controller (2DOF)/Sum/Sum_PID/Sum' are involved in the loop.

Component:Simulink | Category:Model error Input ports (1) of 'electrical/Solver Configuration' are involved in the loop.

no initial input value for PID due to feedback. Try to use the block "Memory"

Thank you very much for the response. I have not been able to test the proposed solution yet.

I am getting another error. - I have not been abler to connect the Simulink-PS and PS-Simulink models.

Sorry, i was sleep. Use electrical sensor for transmite to PS block

Hello Alex - I see two Electrical Sensors.

Thank you that solved the problem
