Oh so sorry, i thought what i have given is the general representation of a state space equation, where x is the state variable, u is the input and y is the output. and yes, "x(dot)" is the derivative of x with respect to t but y is just y.
Hi,
given the state equations of a system,
x(dot) = Ax + Bu
y = Cx
is the impulse response function of this system C(e^(At))B? If not, how can i identify the impulse response from a given state equations? Please advise. Thank you.
i need to convert my transfer function to t-domain format and then plot the graph of the equivalent t-domain equation. i am using the ilaplace function to convert the s-domain transfer function to the t-domain equation.
my code is
>> f = (s + 3.1)/(s^2 +3.1*s + 2.23)
f =...
Hi lanedance,
Thank you for your reply. I confused myself and is able to get the answer already.
The problem was that i have this A1 2x2 matrix, e.g. [1 2; 3 4] and i have another A2 1x1 matrix [5]. I wish to add them together, i.e. A = A1 + A2. At first i thought that the size different...
i have two sets of state equations:
1) x(dot) = (2x2)x + (2x1)u
y = (1x2)x
2) x(dot) = (0)x + (1x1)u
y = (1x1)x
given the above, since A, B and C are of different sizes, how can i add the A from 1) and 2) to get a combined A? Is that possible? Please advise. Thank you.
