Hello everyone, I m trying to plot acceleration vs time graph in Simulink for the quarter car model. As I m taking the output from this point as I have attached the pic the G.A PID is giving more acceleration value than the passive system. Can u suggest me what I m doing is correct or wrong or there is another way we can plot the graph for acceleration vs time?

I cant share my model. If u can give me some idea. I can give u screen shot of dispalcement curve.

Still, the same problem is occurring. My doubt is that the point what I have marked in 1st photo is correct to point to take acceleration value.

Since we do not know your model, there can be several situations for this:
1- You may have modelling error.
2- You may have your PID incorrectly tuned.
3- Your solver may not be suitable for what you are doing.
4- Your step size may become too small during the simulation.
etc. etc.

Ideal PID with nonlinear MR damper for vibration reduction.

Well, with this set of informations, all I can say is said in my initial answer. The rest is yours.
