Good day everyone. How do I simulate nonlinear system in open loop in matlab? I have this nonlinear system and I want to observe the response before applying controller. How do I do that? Please help with the code. Thanks.

Basically you need to define the set of ODE's (ordinary differential equations) that define your system and then solve them. MATLAB has many routines for solving ODE's, Please see the documentation at https://www.mathworks.com/help/matlab/ordinary-differential-equations.html?s_tid=CRUX_lftnav
After you have attempted to code up a solution, if you are still having problems, please attach your code and explain the specific problems you are encountering.

It is little bit tricky to apply your input vector to the system of equations. One approach is explained in https://www.mathworks.com/help/matlab/ref/ode45.html in the example ODE with Time-Dependent Terms
I assume you do not have Simulink. In Simulink you can do everything with block diagrams and it is very straight forward to drive your blocks with a known input vector.
