I want to simulate a nonlinear and differential equation with input like a linear equation using matlab simulink.
I know how to solve with mfile but I want to learn using the simulink.
Dear friends
Thanks for your answer but i have the "U2" term in my equation and I can't use integrator block
can u introduce me some paper that have this models
Simulink is a time domain platform in which all inputs can be defined as time series. You can manipulate the input through integrator, derivative, gain, sum, etc. blocks and put the flow in a closed-loop to solve the equation. Attached screenshot is a simple Simulink model of a multi-story building subjected to an earthquake. In this specific case, all multipliers (M, C, and K) are square matrices and the variable (u) is a vector denoting lateral displacement of each story during the earthquake. In this example the input is Ug which is ground acceleration and absolutely irregular. This specific example is a linear problem but you can easily use Simulink to address nonlinear problems as well.
The simple pendulum equation is a good example to non linear equations. There are several simulink models around internet.
