Use the A, B, C, D matrices of the system sys S S to obtain the transfer function and check if the answer is the original one.

For the new system in state space form, say sys S S, check if the eigenvalues of the matrix A and the poles of the transfer function G of s are the same.

Find a state space realization of the second order transfer function defined below.sys T F is a new variable for which ' denom' command is applicable and not applicable to sys four as it is in state space form.* Use ss two tf function for sys three defined earlier

* It is in the form sys TF equal to ss two tf into bracket sys of SS Type sys capital T capital F is equal to s s two t f open bracket sys four close bracket.Switch to Scilab and type on your Scilab Console * The s s two t f command can be used to obtain a transfer function of a state-space system sys S S. For this you can use the function p l z r function and the spec function.* Check whether poles of sys4 are same as eigenvalues of A. The output will have matrices A B C D and initial state x zero.sys four is equal to sys lin into brackets into quotes c comma A comma B comma C comma D close the bracket and press enter.Let us substitute these matrices in the previous command.C is equal to open square bracket minus three space minus six close square bracket.B is equal to open square bracket one semicolon two close square bracket.A is equal to open square bracket two space three semicolon four space five close square bracket.* Define for example matrices A, B, C, D on Scilab console as you see The output will have matrices A, B, C and D and initial state x zero.This is an example for s ingle state, Single Input Single Output.sys three is equal to syslin into bracket into quotes c comma four comma three comma six comma nine close bracket and press Enter.Switch to Scilab and type this on your Scilab Console for prespecified matrices A, B, C and D of suitable sizes.is specified by sys three is equal to syslin into bracket into quotes c comma A comma B comma C comma D close bracket.

If not, please refer to the Scilab tutorials available on the Spoken Tutorial website.* To practise this tutorial, you should have basic knowledge of Scilab. * I am using Ubuntu 12.04 operating system with Scilab 5.3.3 for demonstation Define a discrete time system and plot its step response.Convert between state space and transfer function descriptions.Welcome to the Spoken Tutorial on “ Discrete Time System”Īt the end of this tutorial, we will learn how to:
