How to determine initial condition of PID control?

I want to do a PID control simulation considering the past input and output.

I know the initial condition of the PID controller can be determined; however, I don't know how to calculate it from the data.

An example Simulink model is attached.

The controlled object is transfer function G = 1 / (20 s^2 + 10 s + 1) and the initial output is set to 5.

The reference is initially 0 and changed to 1 at t=5, and the stop time is 50.

I want to reproduce the simulation data during t>=5 with setting stop time is 45.

How can I obtain such data?

Thank you
