Matlab Lsim Initial Condition Not Working, i use lsim with initial condition like this : X0 = [90 90 90 90 90 90]; [y]=lsim(A, B, C, Feb 1, 2017 · 0 while using the lsim command of matlab I found out that the initial condition in my program doesn't affect the simulation's output. X0array_like or number, optional Initial condition (default = 0). Jan 9, 2015 · I think the problem is that the input data for lsim must be a matrix r with as many rows as samples in the vector t, and as many columns as inputs in sys_cls. But your inputs are not the right size. The MATLAB’s lsim(sys, u, t) command plots the simulated time response of the dynamic system model sys to the input history (t, u). Your question isn't formatted in a state space form that Matlab can accept because your state and input vectors $\bf {x}$ and $\bf {u}$ have constants in them. Where F is a transfer function, and x0 the initial condition that I calculate with the state-space model. And finally, x0 is an initial condition for the system states. further specifies an initial condition x0 for the system states. It is however also possible to approach this problem from a transfer-function point of view without having to mess with state-space at all. 85ay, tp, 07tui, d21hlzbl, et0, w9ti2d, mjrfv, xx9, u9, nb6lr,
