Hi all, In my simulink file, there is PID controller and s-function block diagram.Refer below

My manipulated variable is heat, control variable is reactor temperature. so, my result of reactor temperature without controller is as below:

However, after put in proportional parameter until 2.3e4, there is no oscillation on my reactor temperature result, only got this result,

i changed a lot of numbers for proportional parameter but still no oscillation appear.if the maximum number,only straight line result comes out.i do not know what should i do.I hope somebody can help me... Thank You

your images do not display, so hard to help you without seeing the model
