LSIM initial condition code
显示 更早的评论
Let x(0) = 0 and u(t) = 2, for t >= 0. Obtain a plot of y(t) for 0 <= t <= 20 using the lsim command.
My sys function is ready but I cannot set the initial values in the question above. How can I do this?
lsim(sys1,u,t) This is my code.

Staring from MATLAB R2024b, one of the ways you can specify the initial conditions for simulating a state-space model in the lsim function by a vector xinit having one entry for each state in sys as shown below:
% Initial condition
xinit = 0; % Initial state, x(0) = 0
% Simulate the system response
[y, tOut, x] = lsim(sys1, u, t, xinit);
Refer to the following documentation links to read an example illustrating the same and the details about the initial condition input argument:
