You should be familiar with the step responses of first and second-order systems; this will allow you to make an educated guess also for higher order systems. It only takes a minute to sign up. - Looking at the root-locus plot, we can see that the real-valued pole is (a bit) closer to the imaginary axis than the complex-conjugate pole pair. Taking the Z transform of the impulse response, H ( z) = 2 1 1 2 z 1 1 Hence, the Z transform of the step response is S ( z) := H ( z) 1 z 1 = = 3 1 z 1 2 1 1 2 z 1 Taking the inverse Z transform, we obtain the step response s ( n) = { 3 2 ( 1 2) n if n 0 0 if n < 0 Share Improve this answer Follow We can use an impulse as an input to derive the frequency response.

If you also have the System Identification Toolkit, you can do all of this from Signal Express. I think I understand why you wrote (7) with the scaling (since it seems to follow from the properties of Laplace Transforms). Unit impulse response plots for some different cases This subsection contains some more plots that show the effect of pole locations and help illustrate the general trends. The step response of a system is defined as its response to a unit-step input, \ (u (t)\), or \ (u (s)=\frac {1} {s}\). If you look at that diagram you see that the output oscillates around some constant value finally settling on it: the frequency of these oscillations is the damped frequency. Looking at your graph I'd say that that distance is about one second, so the damped frequency should be approximately 0.5Hz, i.e. \omega_\mathrm{d} = \omega_0 \sqrt{1 - \zeta^2 }\\ This is my y-axis right there. In you apply the derivative to this step response, then you will get the impulse response. Yes, you are right. To use the step response method, input a step pattern with a fast rising edge to your system. Now let's recap: How to find natural frequency from graph/plot of MATLAB Simulink? something directly in terms of $\omega_n$, $a$, and $b$)?

For those particular values of a and b, the denominator is quite easy to factor (poles at (s/w)= -1, and +/- 120 degrees). How to find the system response given the transfer function without using Laplace transforms? Now we have to find the transfer function given the output data. $$\omega_n=\frac{\omega_d}{\sqrt{1-\zeta^2}}\approx3.3\text{ rad/s}$$ If the damping ratio is 0 they don't settle, if it's above unity you don't have oscillations but just a nice exponential. where: u (t) - input y (t) - output Both input and output are variable in time. This is then very easy to solve for the inverse transform, providing the impulse response, here given as: g ( t) = e b t + e a t Step Response The above shows how to solve for the impulse response, which is the inverse Laplace Transform of the transfer function G ( s). The resulting plot is shown below. y(t)= dy(t) dt y ( t) = d y ( t) d t Recall that the unit step response is a zero state response. (Normalize in case it was not a unit step).

The left-hand side is the steady-state value of a step-response (i.e., it is the value of the response as time goes to $\infty$ of a one-unit constant input), and so the steady-state gain is $|\lim_{n \to \infty} y(n)| = \lim_{n \to \infty} |y(n)|$. Use scope or toWorkspace block to obtain the response. We'll do this by analyzing the unit step response of a second order control system in the frequency domain, before converting it into the time domain. So, r ( t) = u ( t) Apply Laplace transform on both the sides. To find the output, we multiply the transfer function by the input, and solve. Like turning on a switchthe vertical portion of the step function has an infinite derivative. Now if you run the 'step' command you will see the same response as you see in the model (except the step command here is injected at t = 0 rather than t = 1) That is important, http://en.wikibooks.org/wiki/Control_Systems/Transfer_Functions, http://www.ijcaonline.org/volume10/number6/pxc3872002.pdf.
