Error evaluating parameter 'SampleTime' in 'twentyfourpulse/VCIMD/Unit Delay4': Undefined function or variable 'ts'.

PLease help me out,my project date is soon approaching

Your model has a block sample time set to the variable 'ts', which needs to exist in the workspace. You can create this variable and assign it a reasonable value in the base workspace. Alternatively, if you're not sure what the value should be, you can double-click on the block 'twentyfourpulse/VCIMD/Unit Delay4' and change the sample time from ts to -1.

This page will help you immensely: http://www.mathworks.com/help/techdoc/matlab_prog/f10-60570.html It tells you how you can debug your program, like how to set a breakpoint and examine variables at that point in your code. You will see that when it comes time to use ts, that ts doesn't yet exist - it has no value and doesn't even exist.
