Well, I have checked your model. You defined your control signal as Joule, and it almost rises from zero to its peak value in no time. This is not realistic since you arranged your Kp coefficient higher than 700. In simulation, it may give you a fine result, but in reality, since the control signal applied on the system is mostly voltage, you can not increase your Kp coefficient this much. Therefore, to make your control process more realistic, I suggest you to either put a saturation element in front of your control signal or redesign your controller. Note that mostly the energy given to the system is generated by an electrical source, which means you have to control the voltage level coming out of your driver circuit.

Hi cvklpstunc. I guess I need to stick with this as the deadline is tomorrow. But if in case you tried it and come up with a better tuning with lower values for the control signal, I will be glad if you can pass that to me :) Although, I already adjusted my proportional gains to around 500 and that is by far I think my best tuning. Thanks
