You can create a state-space model object by either specifying the state, input and output matrices directly, or by converting a model of another type (such as a transfer function model tf) to state-space form. For more information, see State-Space Models. You can use an ss model object...

To convert the above VARMA model to a state space model (in innovation form), we may use the functionj toSS. The function is.innovSS checks whether the input is an “innovation form state space” object. > ss = dse::toSS(arma) > ss F = [,1] [,2] [,3] [,4] [,5] [,6]...
Examples Create State-Space Model with Identifiable Parameters Create a 4th-order SISO state-space model with identifiable parameters. Initialize the initial state values to 0.1 for all entries. Set the sample time to 0.1 s. A = blkdiag([-0.1 0.4; -0.4 -0.1],[-1 5; -5 -1]); ...
Create a second-order transfer function with uncertain natural frequency and damping coefficient. w0 = ureal('w0',10); zeta = ureal('zeta',0.7,'Range',[0.6,0.8]); usys = tf(w0^2,[1 2*zeta*w0 w0^2]) Uncertain continuous-time state-space model with 1 outputs, 1 inputs, 2 stat...
Different state space representations are called different realizations. It is worth noting that state space representations of systems are not uniquely defined. For LTI systems, different sets of state space matrices may correspond to the same transfer function, being related by similarity transform. ...
Do the steps of converting this space to transfer function include any laplace ? or just we do get [SI-A]-1 and then transfer function is = C* [SI-A]-1 * B As [1 0] * [s-1/det -0.5/det ; 0.5/det s-0.5/det] * [0; 1] = -0.5/s^2+s+0.5 I mean do we need any...
