I am trying to plot a non-linear model in order to compare it with it's linearized counterpart.
I am following this paper Nonlinear Model & Controller Design for Magnetic Levitation System and trying to reproduce the results the authors obtained. In particular I am trying to plot:
The above equations can be represented in vector format as follows:
I found no references on how to plot non linear state space model representations on MathWorks.
The Simulink state-space block is used to implement linear state-space systems and not non linear ones.
So, how can I plot the response of a non-linear state space model in Simulink ? Any suggestions would be appreciated.
