|-
|00:01
|Welcome to the spoken tutorial on''' Xcos: Scilab Connected Object Simulator.'''

|-
|00:07
|'''Xcos''' is a '''Scilab package''' for modeling and simulation of dynamical systems. It includes both '''continuous''' and '''discrete''' systems.

|-
| 00:17
|In this tutorial you will learn
* What is '''XCOS'''.
* What is '''palette'''.
* Build block diagrams in '''Xcos'''

|-
|00:26
|
* Setup the parameters of blocks.
* Setup the simulation parameters.
* Simulate the constructed block diagram.

|-
| 00:35
| To practice this tutorial, Scilab should be installed on your system.

|-
|00:40
|I am using Ubuntu Linux 12.04 and Scilab version 5.3.3 for demonstration.

|-
| 00:48
| Open the '''Scilab console''' window on your computer.

|-
|00:52
|Go to applications and select '''Xcos'''OR
Type '''xcos''' in your '''Scilab console''' window and press '''Enter'''

|-
| 01:02
|By doing this, two windows will open. The two windows are'''Palette browser''' and '''Untitled-Xcos''' window

|-
|01:14
|In '''Palette browser''', you will find different types of blocks '''Commonly Used Blocks''' '''Continuous time system blocks''' '''Discrete time systems blocks'''and many more.

|-
|01:26
|The other window, '''Untitled-Xcos''' is blank, with grids.

|-
|01:31
|We will now simulate a '''first order system''' with a''' step input'''.

|-
|01:36
|To begin, I will select a '''transfer function block''' from the '''Continuous time systems palette'''.

|-
|01:43
|Drag this block to the '''Untitled-Xcos''' window.

|-
|01:48
|Select the required source in the '''Sources palette'''. I will scroll down and use the '''STEP FUNCTION block'''.

|-
|01:56
|I will drag and place it before the '''transfer function block.'''

|-
|02:01
|Similarly, the output is displayed using the '''CSCOPE block''', which is available in '''Sinks palette.'''

|-
|02:08
|The '''CSCOPE block''' is placed after the '''transfer function block.'''

|-
|02:13
|The red input port in '''CSCOPE''' denotes that this block is an '''“event driven” block.'''

|-
|02:19
|It needs an '''event''' input for execution.

|-
|02:22
|An '''event generator block''' is available in the '''Event handling palette.''' The name of this block is '''Clock underscore c'''.

|-
|02:34
|Drag and place this block above the CSCOPE block.

|-
|02:39
|We have collected all the required blocks to do the simulation.

|-
|02:44
|Let us now connect the blocks together.

|-
|02:47
|Select the '''output port''' of '''step function block''' and connect it to the '''input port''' of the '''transfer function block.'''

|-
|02:55
|Notice that the selected '''input port''' gets highlighted in green colour.

|-
|03:00
|Similarly, connect the remaining blocks as shown.

|-
|03:05
|Now we will set the parameters of each block.

|-
|03:10
|First, go to the '''step block''' and double-click on it.

|-
|03:14
|A pop up window appears, asking for the value of '''Step Time, Initial Value''' and '''Final Value'''.

|-
|03:23
|'''Step Time''' is the time at which the '''step change''' will occur.We will keep it as 1, which is the default value.

|-
|03:32
|'''Initial Value''' is the initial output value of the '''step function'''. We will keep it as 0, which is the default value.

|-
|03:41
|'''Final Value''' is the output of the '''step function''', after the '''Step Time''' is lapsed.We will change it to 2.

|-
|03:50
|Click on '''OK'''.

|-
|03:52
|Follow the similar procedure to configure any other block.

|-
|03:56
|For '''transfer function block,''' the following configuration is required. '''Numerator''' value in''' laplace domain''' has to be entered.

|-
|04:05
|We will keep it as 1, which is the default value.

|-
|04:09
|'''Denominator''' value in '''laplace domain''' has to entered. We will change it to '''2 asteric s plus 1'''.Click on '''OK'''.

|-
|04:20
|Double click on '''CSCOPE block,''' to configure the following parameters.

|-
|04:25
|The value of''' Ymin''' and '''Ymax''' should be set, depending on the range of the value, of the variable to be plotted.

|-
|04:34
|Set the value of '''Ymin''' to 0.

|-
|04:38
|Since I have given '''step input''' as 2, to display the output on graph, I should change the '''Ymax''' to any higher value.

|-
|04:46
|We will change it to 3.

|-
|04:50
|Make a mental note of the default value of the '''refresh period'''.The default value is 30.

|-
|04:57
|We will keep the other parameters unchanged.Click on '''OK'''.

|-
|05:02
|Now go to the '''Simulation''' in menu bar and click on '''Setup'''.

|-
|05:08
|A pop up window appears.

|-
|05:11
|We will change the value of '''Final integration time'''.'''Final integration time''' decides how long the simulation will run.

|-
|05:20
|Recall the value of '''refresh period''' of the''' CSCOPE block.'''

|-
|05:24
|I will keep the value of '''Final integration time''' equal to the value of '''refresh period''' of '''CSCOPE block'''So, I will change it to 30.

|-
|05:34
|Keep the other parameters unchanged. Click on '''OK'''.

|-
|05:39
|Now press '''Control S''' to save the file, with a suitable file name.I will save it as '''firstorder.xcos'''

|-
|05:50
|To start the simulation, click on the '''Start''' button, available on the menu bar of '''Xcos''' window.

|-
|05:58
|A Graphic window will open, showing the '''step response''' of the first order '''transfer function.'''

|-
|06:04
|We can save this plot as an image file.

|-
|06:06
|To save the graph, go to the '''File''' menu and click on '''Export to''' option.

|-
|06:12
|I will name it as firstorder.png and click on '''OK'''

|-
|06:20
|There are certain parameters which we chose to keep as the default value. These can be changed.

|-
|06:26
|For example In the''' Clock underscore c block''', the '''period''', which means the '''sampling period''' and '''initial time''' can be set.

|-
|06:36
|In the '''CSCOPE block,''' the '''output window number, position, size, buffer size , graph color''' etc can also be set.

|-
| 06:46
|Pause the video here and solve the exercise given with the video.

|-
|06:52
|Simulate a '''second order transfer function''' with '''damping ratio''' of 0.5 and '''angular frequency''' equal to 1.

|-
|07:01
|Try changing the color of output graph.

|-
|07:04
|Using the first exercise, plot the '''Step input''' and the '''output''' in a single plot window.

|-
| 07:11
|Now let us summarize.In this tutorial we have learnt to:
*Create '''Xcos simulation''' diagrams using the '''palette browser'''
*Configure each block as per the simulation requirements

|-
|07:22
|
*Setup the simulation parameters
*Save the output plot.
