This MATLAB function converts a continuous-time or discrete-time single-input transfer function into an equivalent state-space representation.
Find the response of the system to a positive unit impulse excitation on the second mass. [b2,a2] = ss2tf(A,B,C,D,2); y2u1 = filter(b2(1,:),a2,ux); y2u2 = filter(b2(2,:),a2,ux); Plot the result. The transfer function gives the same response as the state-space model....
Use tf to create real-valued or complex-valued transfer function models, or to convert dynamic system models to transfer function form.
This shows the relationship between the impulse response and the transfer function of an LTI (Linear Time-Invariant) system. It also illustrates how to obtain the output of the system to an input using the transfer function or state space representation through MATLAB/Simulink. Refer to ...
For example, convert the state-space model sys_ss to a transfer function. sys_tf = idtf(sys_ss);For a more detailed example, see Convert Identifiable State-Space Model to Identifiable Transfer Function For information on functions you can use to extract information from or transform idtf ...

Use the state-space model to compute the time evolution of the system starting from an all-zero initial state. Plot the acceleration of the mass as a function of time. Get rng("default") u = zeros(1,N); u(1:N/2) = randn(1,N/2); y = 0; x = [0;0]; for k = 1:N ...
A structure has been given to me with y(t) against t(sec) When I plot it I get this graph: What I need: I need to find the trasnfer function for the conditions above. I know that I can find it analytically by finding Mp, Zeta, Wn and etc... Is there a shortcut to find the...
An algorithm for computation of transfer function matrices of generalized linear multivariable state-space systems is presented. To improve the numerical performance of the algorithm, as far as possible only orthogonal transformations are used. The algorithm has been tested on a VAX 11/785 using ...
