Hi...I have a specific length of signal.I don't know the length of the signal .I should repeat the signal.If youu see in the file I have already created a single cycle but sending the speed and time data in the look up table and got the single cycle .I want to repeat the cycle.

It is somewhat difficult to repeat a user defined signal input in Simulink. In your case though, I can think of a solution.

Since you have the single cycle data in the 1-D lookup table, your must know the time duration of your single cycle signal. Let's say the data is from time 0 to time 8.4 seconds, you can add an "Interpreted MATLAB Function" block between the Clock and the lookup table block. The function you need to specify is mod(u,8.4), you will then get an endless repeat of your single cycle signal.

In the code you have mention the length of the vector as 80 know .Here the problem is I should also calculate the length of the vector because the single generated is according to the data collected in time.So I should measure the length of the signal ,see where it ends and reset it again to zero and repeat the same.
