As a short I have a following question ; -In my thesis I use X Plane(aircraft simulation program) and Simulink. I get aircraft values during the flight like pitch degree directly from X plane through UDP connection to Simulink. Here is everything fine. The problem is I want to insert a time delay for to calculate another parameter like pitch rate (which is pitch_degree(t) - pitch_degree(t-1), current (at time t) pitch degree minus before( t-1)pitch degree). Question is how can I do this? In simulink there is discrete blocks like Unit Delay Block or continous blocks like Variable Time Delay. I try both of them but it seems not functioning. Is there any one who have any idea how to solve this problem
Many thanks from now Tahir

Perhaps the solution in this blog entry will help. But more experienced Simulink users than me might recommend a simpler approach.
