11.15. Impulse Response of Control Systems
The MATLAB commands used to obtain the impulse response are similar to that used for obtaining step response and are:
- impulse (n,d)
- impulse (A,B,C,D)
- [y,x,t] = impulse (n, d)
- [y,x,t] = impulse (n, d, t)
- [y,x,t] = impulse (A,B,C,D)
- [y,x,t] = impulse (A,B,C,D,iu)
- [y,x,t] = impulse (A,B,C,D,iu,t)
The commands (a) and (b) directly plot the unit impulse response, whereas for commands (c) to (g), the plot command has to be used for obtaining unit impulse response plot.
The vector t in (d) and (g) commands, is a user-defined time vector. It specifies the time at which the impulse response is to be computed.
The command impulse(A, B, C, D) produces a series of unit impulse response plots, one for each input and output ...
