Error getting characteristics from Linear Analysis Tool and PID Controller

I am trying to get characteristincs with the PID parametrs wich i callculated myself and set to PID controller and want to get characteristics from Linear Analysis Tool. But if there is PID controller i cant get this characteristics because plant response goes to infinity. While i can get acces to those characteristic if i use PID Tuner.

How could I fix this error to get results from plant without Tuner app?

Hi Vasiliy,

Change the analysis point at the output of the plant from 'Open-Loop Output' to 'Output Measurement'
