First, build the model in simulink. Then plot the output signal (i.e. current) vs. time

"plot" can be used for time domain while "Bode" can be used for frequency domain

Actually, I remember I built an active suspension system with LQR control several years ago. If you want it, please email me and I may send you by email if I can find it from my previous laptop.
