Hi ,I am using PID auto tuning for my circuit.But what i found is my Kp=0,Ki=-1;I have doubt on these values And also getting a steady state error of 60 Volts and the actual value is 400 volts.So how can i set my steady state error before tuning.And Could anyone tell me the exact way of auto tuning.I have a doubt that whether the tuning work fine or not.I am using Interleaved boost converter.And the control system has 2 PI controllers.One for inner Current loop and outer voltage loop.

Hi check this mathworks article https://in.mathworks.com/help/slcontrol/gs/automated-tuning-of-simulink-pid-controller-block.html on PID Controller Tuning in Simulink.
And also this video https://in.mathworks.com/videos/pid-control-made-easy-81646.html explains about PID controller and its tuning.
